Leon Trotsky compared formal logic to dialectical logic as a still photograph 
to a movie. A photograph can provide a myriad of information about a particular 
situation as it was in the instant it was taken but that image is only one 
moment in a sequence of events. The photo doesn’t tell us what has gone before, 
and we can only guess what happened next. A movie can show us the narrative 
sequence leading to that scene and beyond.

Marxists pay homage to formal logic and recognize it is necessity for all of us 
as we deal with the world in our domestic lives, work and to research in every 
branch of science.

A = A,

A is not = B

All of our systems of classification in every branch of study from astronomy to 
zoology and library book cataloguing employ these basic rules of logic. 
Humanity owes a great debt to Aristotle (384-322 BC) who first identified the 
laws of logic over two millennia ago, that we employ constantly today.

However close inspection of every phenomenon in the natural world and human 
society reveals that the one constant in the universe is change.

A is not A forever.

“In nature nothing remains constant. Everything is in a perpetual state of 
transformation, motion, and change. However, we discover that nothing simply 
surges up out of nothing without having antecedents that existed before. 
Likewise, nothing ever disappears without a trace, in the sense that it gives 
rise to absolutely nothing existing at later times. This general characteristic 
of the world can be expressed in terms of a principle which summarizes an 
enormous domain of different kinds of experience and which has never yet been 
contradicted in any observation or experiment, scientific or otherwise; namely, 
everything comes from other things and gives rise to other things” —quantum 
physicist and Marxist philosopher David Bohm.

In that sentence Bohm has summarized the essence of dialectical materialism.

Marx and Engels considered all of the early philosophers, particularly 
Aristotle, to be instinctive dialecticians but those predecessors did not have 
sufficient scientific knowledge to understand the motive forces of change. They 
lived in a world where the established view was that all change resulted from 
the behavior of capricious gods and other supernatural beings. Socrates 
(c470-399BC) would be condemned to death for suggesting that his students 
question that presumption. It would take the accumulated experience of more 
than 2000 years of developments in society and science to reveal the forces 
driving the dialectical phenomena in the material world.

When we wish to investigate nature in more detail or over time it soon becomes 
clear that everything is changing so that the logic of A = A no longer applies.

A = A and to non-A at the same time. 

A is becoming into B. 

It is this contradiction to formal logic which is at the heart of dialectical 
logic.

This is the law of “the unity of opposites.”

Everything is at once itself and in the process of becoming something else.

The changes in the natural world are not beyond human understanding. They have 
characteristics and patterns which are recognized and classified into the laws 
of science. It was the German philosopher, Georg Frederick Hegel (1770-1831) 
who, basing his studies on 2000 years of philosophical speculation, scientific 
progress and influenced by the revolutionary political climate during his young 
life who identified the general laws of dialectics that are in operation 
everywhere in nature and society. (Warning: Hegel is not an easy read.)

For Hegel, all of nature was a manifestation of the original “notion” or 
“Absolute Idea” which finds itself through progressive development in the 
material world to result in absolute self-knowledge. Hegel was an idealist. For 
him the idea came first and material reality its product and means of 
self-realization. For materialist Marxists the external world is primary, and 
our thinking is the product of the activity of our brains absorbing through our 
senses, integrating, processing, analyzing and reflecting on the information it 
is receiving. Dialectical thinking is derived from the dialectical nature of 
reality.

We think using the principles of formal logic as they are true most of the time 
and are necessary and sufficient for many activities. But nature is not static 
and other methods of thinking are needed to understand how and why changes 
occur. That method is dialectical materialism.

It is necessary to start by considering how we obtain and verify our knowledge. 
Marx and Engels solved this issue in philosophy by recognizing that the source 
and confirmation of knowledge is human social practice. In the process of 
carrying out the tasks necessary to live, humans have always acted collectively 
whether it be as hunter gatherers or in modern high-tech industries. Knowledge 
of the world is obtained collectively through the senses of individuals, but 
humans have always lived in social groups so that knowledge and practical 
techniques have always been shared communal products, transmitted down 
generations and preserved collectively.

Marxists start with the view that our knowledge of the material world is fairly 
accurate. Scientific research and practical experience are continually 
expanding and refining our knowledge and deepening our understanding of every 
aspect of nature. In just over two centuries our knowledge of the universe, its 
origin, history and future developments have been elucidated in considerable 
detail from the detailed internal structure of the atom back to the beginning 
of time with the Big Bang. We know the evolution of our solar system and its 
context in the Milky Way galaxy and how our own planet has changed over the 
past 4.5 billion years has left evidence that has been unraveled by science 
charting the universe as it has evolved in 13.7 billion years.

In September 2020 after a four-year mission a human made satellite collected 
material from the surface of an asteroid, named Bennu with a diameter of 500m, 
200 million miles from Earth traveling at more than 100,000-km-per-hour. Having 
orbited, photographed and mapped Bennu, an arm projected from the satellite 
collected material from its surface and is returning with it to Earth for 
analysis. This was a massive collective human undertaking and a monumental 
tribute to our knowledge of the universe, our engineering and mathematical 
prowess.

Evidence of dialectics
Wherever we look in nature, history, sociology and even our daily lives we will 
find evidence of the laws of dialectics that Hegel systematized in his “Logic.” 
It is knowing what to look for.

As a trainee microbiologist I learned to use the compound microscope. My first 
experience was overwhelming and exciting as I looked into a world I didn’t know 
existed. I had to learn how to set up the microscope and to focus on specimens. 
With years of experience, I learned to identify different microorganisms, 
hundreds of different cell types and to distinguish healthy from diseased 
tissues. Electron microscopy would lead me to recognize intra-cellular 
structures, organelles and viruses.

So, too, with dialectics. Once the basic laws are known we can recognize them 
in operation wherever we find them and with practice, our skills as with any 
activity will improve and be refined.

“The dialectics of things produces the dialectics of ideas not vice versa.” 
Lenin taught “The laws of logic are the reflections of the objective in the 
subjective consciousness of man.”

Trotsky warned of this too:

“You can’t just foist dialectics on facts but must derive it from the facts, 
from their nature and their development...”

We cannot impose dialectics on nature or science or any field of 
investigation—they are either there or they are not. Yet we find dialectics 
wherever there is change. However, once we are familiar with dialectics and 
science, we realize that dialectics are the logic of evolution.

Dialectics and the triad
The concept of dialectics goes back to Plato (437-327 BC) where contradictory 
points of view are presented in a debate. We know of Socrates views only 
through Plato where he presented debates between Socrates and opponents in a 
backwards and forwards exchange of opinions. As a result of this dialectical 
debate views change and a deeper level of understanding of philosophy will 
emerge.

Hegel knew that the dialectical method was an essential to philosophy, but that 
Plato’s ideas were insufficient. The opposites presented in a dialectical 
debate were not mutually exclusive but facets of the same thing, that 
contradiction was necessary and when resolved, a higher level of understanding 
is reached. For Marx and Engels, the contradictions in ideas have their origin 
in the material world which is ever changing. The driving force of those 
changes are the real internal contradictory forces active in all things 
including nature and society.

Dialectics is frequently illustrated in the form of a general triad. Thesis + 
antithesis = synthesis.

A useful but simplistic example is:

Sodium—a highly reactive metal + chlorine—a poisonous gas together forms sodium 
chloride (common salt) an essential for life.

(The triad formula was never used by Hegel and I have not come across it in 
Marx or Engels either.)

This example can be useful as an introduction to the concept of the unity of 
opposites generating something qualitatively new.

Contradiction
Contradiction or the “unity of opposites” is the fundamental motive force of 
all change.

The Big Bang first produced light (electromagnetic radiation) which has no mass 
but has the properties of a particle and a wave and all physical matter from 
atoms to galaxies are products of light. Energy and matter—two opposites—are 
interchangeable in the natural world. (E=M times C squared)

>From the simple to the highly complex from the inner workings of the atom to 
>the expanding cosmos, to detailed investigations of life’s processes inside 
>organisms, the interactions between opposing forces and phenomenon are 
>universal.

The components of the nucleus of an atom are massless electromagnetic radiation 
“condensed” into subatomic particles and some such as the Higgs boson acquire 
mass.

The unity of the positively charge nucleus with the negatively charged electron 
is the fundamental building block of all chemical matter while the exchange and 
sharing of electrons between atoms is the principal mechanism of chemistry.

A star is a dynamic equilibrium between gravity and the thermonuclear reactions 
at its core where hydrogen is being fused to form helium.

Eventually the hydrogen fuel will run out and the star will implode, then 
explode sending debris containing all the chemical elements of the periodic 
table up to iron into space. The dying stars create all of the chemical 
elements necessary to make planets like ours and water the most abundant 
chemical compound in the universe. From some combination of these inorganic 
materials life will emerge on Earth and from unconscious chemical matter 
eventually a combination will produce consciousness and the ability to reflect 
on the dialectics of its own nature. 

Consider the chicken embryo developing within its shell of inorganic calcium 
compounds. Absorbing the nutrients from the yolk the embryos’ cells multiply 
transforming the energy and nutrients into internal organs and limbs—the 
non-living yolk is transformed into a live chick. Eventually the chick breaks 
free from the confinement of the shell to a qualitatively new life. If it 
continues to be fed, the chick’s baby feathers will be replaced by adult ones 
which may allow the gravity bound bird to fly. In time, if the bird is 
fortunate to live to sexual maturity and find a mate, it will contribute to the 
next generation. It will change from being a dependent to being independent 
then, a parent. At some point in this seemingly repeated cycle of life, some of 
this successful line of birds will produce an egg that hatches to release a 
type of bird that is qualitatively different from its ancestors and, if able to 
reproduce, will be the first generation of a new species. (The egg came before 
the chicken.)

Whenever we investigate any natural phenomenon, we discover that nothing is 
permanent. Some changes are imperceptibly slow to our senses, on our human time 
scale—the Scottish Highlands were as high as Everest (8,828 meters) 600 million 
years ago but Ben Nevis the highest has been reduced to 1345 meters. Other 
processes we can watch, monitor and sometimes control such as gardening, 
cooking and scientific experiments. Yet others are so fast that all they leave 
is the trace of their having been, such as the identification of the Higgs 
boson.

Close examination of a group of A shows that all As are not identical. In 
microscopic examination no two microorganisms or cells or viruses are 
identical, yet we can classify them. For expediency and practicality these 
negligible differences are usually ignored while the quantity may be the most 
significant factor. The trained eye of a hematologist however can examine a 
specimen of blood in the microscope, recognize minuscule but significant 
differences in cells and so, can detect and diagnose leukemias or anemias. In 
these cases, A is not A with an expert’s close inspection and that may be a 
matter of life and death.

When we investigate chemical composition of individual living cells, we 
discover that they contain not only organic molecules such DNA, proteins and 
fats but inorganic chemicals such as sodium, potassium, chlorine and is 
overwhelmingly water. It is the constant movement of materials into and out of 
the cells and the constant regeneration of the internal organic structures that 
are the essential activities of life. Life is the product of the unity of 
opposites, the organic and the inorganic. Everything that lives will eventually 
die but that is not an event, it is a process, and not the end to the story. 
Corpses are food for a multitude of organisms from the microbial to the carrion 
eaters.

All living things inhabit an environment which includes other living beings. 
Whether it be in a pond, or inside a human body, every living cell is in a 
community and in communication with many others. In the pond there is a lot of 
eating. There are carbohydrate producing plants which become food for 
herbivores who in turn become prey to carnivores who are themselves prey to 
other carnivores and parasites. All living organisms produce waste which 
becomes food for other life forms.

The ecology of the pond is determined by a lot of dialectical processes but 
above all by the essential dialectics of life and death.

Within the bodies of every living multicellular organism there are similar 
dialectical processes at work—life and death, growth and decay. In the course 
of living every body is in a constant state of change. Millions of cells are 
dying while others are being generated every second of our life. While the body 
is growing by the production of new cells others are being induced to commit 
suicide (apoptosis) by specialized cells sculpting each tissue and organ into 
the form that will carry out a particular function such as liver, skin, brain 
or skeleton.

Reaching maturity for every organism is the combination of cell multiplication, 
differentiation and destruction. In humans, before we have reached sexual 
maturity, the processes of degeneration and ageing have already begun.

When we examine other phenomena that are presented as polar opposites by formal 
logic, we see that they too are inseparably linked.

Necessity and chance
That you are reading this means that you necessarily have an uninterrupted 
ancestry that goes back some 3.5 billion years to LUCA the common ancestor of 
all life on Earth. In that period countless trillions of other organisms have 
died, many of them to feed our ancestors each of whom survived long enough to 
produce descendants. Most of the species that ever lived are now extinct. It is 
the accumulated chance survivals through the immediate trials of life and five 
mass extinctions that were necessary for you and I to be here.

In sexual reproduction a sperm makes a chance encounter with a receptive egg as 
the necessary event. Two haploid cells with different ancestry (usually) 
combine their genetic material DNA to produce a unique individual. The DNA in 
each of the gametes is itself the product of the random shuffling of the 
genetic material each parent has inherited from their parents in such a way 
that unless cloned every individual human has a unique genetic profile. This 
process has been necessary for every one of us but there have been a myriad of 
chance events that lead to the evolution of humans and to each of us as living 
individuals.

A dandelion seed-head releases 100s of new seeds into the air that may travel 
for many miles. Most will not survive to germinate but by chance a few will and 
grow to maturity be fertilized (not an absolute with all dandelions) by a 
chance visiting pollinator— bee, a butterfly or a beetle and give rise to 
another generation of seeds. It may be the repetition of a seemingly endless 
cycle, but detailed investigation will show that gene shuffling means each seed 
is a unique individual. Some from each generation have to survive the hazards 
of natural selection or the species will become extinct. In time this seemingly 
random process will reveal the effects of natural selection. There are over 200 
species of dandelions which have evolved from a common ancestor, each with a 
unique genetic profile, morphology and ecological niche all formed by chance 
mutations in their DNA together and selected by the opportunities and 
challenges of the world. The fossil record shows innumerable plant and animal 
species that are now extinct but the vacancies they left were soon filled often 
by unrelated organisms.

One species’ demise is an opportunity for others.

Cause and effect
Cause and effect are inseparably linked in every event in nature. Every new 
effect produces a change in its environment—it has become the cause of further 
changes.

In all chemical reactions as the product accumulates it becomes a break on its 
own production, which is referred to as negative feedback. The living body is 
dependent on an infinite series of regulator mechanisms that control the 
internal environment of the body and maintain it despite both external and 
internal challenges. These mechanisms known collectively as homeostasis all 
operate by signals that affect the activity of cells and organs. The 
consequences of the actions are reported back so that the effect is now a new 
cause. This results in a dynamic equilibrium being established which maintains 
the body’s essential functions through internal disease and injury. These have 
limits beyond which is death.

I will concentrate on one of the parings of formal logic1—the transformation of 
quantity into quality and vice versa.

The first point to make is that quality and quantity are inseparable, 
everything is both of these at the same time which is a dialectical 
relationship. In mathematics there are abstract quantities (x and z) but in the 
real world it is quantities of material things (qualities) that we work 
with—one liter of milk, five apples, two kilos of sugar. Even a single item 
(quality) has some volume, weight and other measurable (quantifiable) 
characteristics.

In nature quantity can profoundly affect quality. The example used by Engels of 
the Periodic Table, which was in its infancy in his day, has been confirmed 
with every element discovered or manufactured in the lab. The addition of a 
proton to the nucleus of an atom changes it into a different element.

In biology a myriad of species of inorganic ions—atoms that have gained or lost 
an electron—have an essential role in every aspect of living processes within 
cells and the tissues of the body.

Atoms and electrons
The loss or gain of an electron can profoundly affect the physical, chemical 
and biological behavior of atoms—poisons are neutralized, explosives tamed and 
both employed in living systems that are dependent upon them. The transfer of 
the hydrogen ion (H+) through a series of stages in cells until it combines 
with oxygen, to form water is the principle means by which our cells obtain the 
energy to facilitate all of the other life processes.

Qualitative change is the foundation of quantitative expansion.

Sixty-five-million years ago a meteor hit the Earth—an event that ended the era 
of the dinosaurs. A relatively unimportant group of animals, the mammals, were 
then able to multiple as never before, migrating and colonizing niches excluded 
to them before. Radiation and multiplication lead to diversification and the 
appearance of many new lineages and species. During that time many species of 
mammals have come into being and become extinct. One particular line of 
primates leads to the evolution of Homo sapiens, a creature, like no other 
before that could not only produce the means of life for itself but could 
reflect on its own origins and take consciously planned measures to affect its 
own future as a species.

Negation of the negation
Everything has an ancestry from which it has emerged. The whole of the natural 
history and the diversity of life on Earth is a manifestation of this 
dialectical law.

All life on Earth is descended from LUCA, a prokaryote, (a microscopic 
single-celled organism that has neither a distinct nucleus with a membrane nor 
other specialized organelles,) a bacterial-like organism which evolved about 
3.5 billion years ago. Her decedents multiplied, displaced any contending life 
forms and diversified being the only form of life on Earth for a time. At some 
point where some aggregation of cooperating prokaryotes (A microscopic 
single-celled organism that has neither a distinct nucleus with a membrane nor 
other specialized organelles) formed an entirely new life form eukaryotes—cells 
with a nucleus. These new organisms also evolved a method of generating genetic 
diversity more rapidly—through sexual reproduction, the combining of genetic 
material from different sources.

Prokaryotic evolution had proceeded slowly over billions of years, however with 
eukaryotes the rate of evolutionary change is accelerated and within a short 
time, complex multicellular organisms appeared. While the most abundant 
organisms on Earth are still prokaryotes, it is multicellular life that has 
dominated for the last 500 million years. In that time there have been five 
mass extinctions each of which created conditions that allowed the emergence of 
new life forms that would radiate, diversify and predominate for a time to be 
supplanted by a life form that emerged from its ranks.

In our own lineage we have primitive ancestors whose unique characteristic was 
a biological experiment, an internal spinal column. For millions of years these 
creatures were not significant but in time they would give rise to fish whose 
relatives, the amphibians, would acquire the means to colonize the previously 
uninhabited land. Some decedents of the amphibians would evolve into 
exclusively land dwelling but “cold blooded” reptiles—a branch of which over 
time evolved into internal heat producing mammals. From our DNA through our 
anatomy, physiology and biochemistry we can still trace the biological features 
our ancestors have bequeathed to us. Each has been a platform from which other 
developments were generated eventually leading to a qualitatively different 
type of organism.

“Negation of the negation” is not a negative concept. The best of the old is 
maintained while escaping from its constraints so that new potentials are now 
presented.

A caterpillar lays its fertilized eggs on a leaf. The eggs hatch releasing the 
caterpillar that was developing inside. The caterpillars are eating machines 
and also an important food source for many birds and animals. Those that 
survive form a cocoon around themselves where the caterpillar body is broken 
down to all but its nervous and respiratory systems then used as material and 
fuel to build a new butterfly. When ready, the butterfly breaks out of its 
cocoon and sets off in search of a sexual partner and, if successful, the cycle 
continues again. Each stage is a negation of the previous stage in the 
butterfly’s life cycle and a qualitatively different form needed for other 
activities.

All complex organisms go through definite stages of development but not as 
dramatically compartmentalized as butterflies and their insect relatives.

The truth is always concrete 
Irrespective of the general laws of dialectics we have discussed, the truth of 
what is happening in the real world is always our starting point. The truth is 
always concrete. The particular laws of dialects are not proscriptions for 
every situation and all time. They are a guide to analysis and action in 
today’s world and will be the foundation for the higher levels of consciousness 
that will emerge with social progress.

Why is any of this important?

First if we want to understand how the world works and then our thinking has to 
correspond to that reality. Everything in the universe is in constant movement 
but that does not make it lawless and unknowable. The specific branches of 
science investigate particular spheres of nature and have their own laws and 
paradigms. The constant that connects all branches of knowledge is dialectics.

Surgeons are encouraged to adopt hobbies such as playing a musical instrument 
or model making both of which require practice, patience manual dexterity and 
concentration. All are skills that they also employ in the operating theatre. 
As recreational activities they are also refining the skills that will be put 
to practical use in the life and death environment of the operating theatre.

So, too, with dialectical thinking, it is a tool like all others that our skill 
in using improves with practice. In our everyday life, of work and studies we 
will encounter dialectical processes constantly if we choose to look, until 
dialectics becomes our natural way of thinking. It is our most important weapon 
in the class struggle. It allows us to identify trends and developments in the 
class struggle so that we can intervene to promote those movements which serve 
the interests of the working class and try to block those that don’t.

Marx and Engels were the first to recognize that history has always been the 
product of class struggles. The desire for socialism and a better life for all, 
among the working class, is a product of poverty and deprivation which are 
themselves inescapable products of the capitalist system. The capitalist system 
produced the proletarian class—a unity of opposites in constant struggle. The 
workers create the wealth which the capitalist class appropriates, and that 
dialectical relationship will only be resolved when the means of production are 
expropriated from the capitalists, directed to social use and the entire 
capitalist state apparatus is destroyed. Others believe that another road is 
possible, but the last few decades have shown that gains made over generations 
by the working class can be removed in an instant.

Sections of the Labour movement may have abandoned the class struggle but the 
capitalist class never does.

Knowledge is the guide to correct actions and that, above all, is the 
importance of dialectical materialism which gives us a more comprehensive 
understanding of the world than any particular branch of science or other 
school of philosophy.

Marx and Engels realized that capitalism had created a dialectical relationship 
of the capitalist class and the proletariat. The poverty and misery created by 
capitalism will only be abolished irrevocably when the proletariat takes 
control of society and runs industry, commerce and farming for need not profit. 
Dialectical materialism is an optimistic philosophy. No situation is permanent. 
The masses cannot be permanently held down or contained and every condition is 
only temporary.

To return to our movie analogy. It has a determined end which must flow 
logically from the proceeding story line. The director may have had options for 
the final cut, but the viewer has to passively accept the outcome. That is 
where the analogy ends, for we have the choice to remain observers or to 
actively participate. For Marxists, that means above all, in the class 
struggle, where dialectical and historical materialism are our greatest weapons.

Professor Hegel became a conservative in his old age and thought that 
constitutional monarchy was the pinnacle of human government. The revolutionary 
of his youth had turned into the opposite, a reactionary, in later life—a 
common enough story.

Dialectics forces us to face the truth however unpalatable. Marx and Engels 
realized that the state is the guardian of capitalism and only with its 
revolutionary overthrow and replacement by the dictatorship of the proletariat 
internationally can socialism be brought about. That knowledge then is the 
foundation for the program, strategy and tactics of revolutionary communists 
and what distinguishes us from other socialists and anarchists.

1 Without going into detail here I have listed a series of pairings that formal 
logic puts in opposition to each other. As a mental exercise look at these 
pairings in contexts that you are familiar with: Subject and object; Host and 
parasite; Growth and decay; Life and death; Cause and effect; Necessity and 
chance; Essence and appearance; Content and form; Self and non-self; Particular 
and universal; Quantity into quality.
