Evgenii : I thank you for your questions, since It helps me to re-examine and clarify my position.

The consciousness of time appears as a consequence of two things: Lack of information and the hability that humans have of learning from experience. Plants and most of the animals have innate set of behaviours or at most, a short learning program that fixes behaviour after the young age. But humans modify their behaviour depending on the past, but not only the past but depending on the ordering of events in the past: In an experiment , as in a love affair or in a battle, the lessons learned depends in the order of the events. If we had not that ability to learn from experience and thus, the need to remember sequences of events, then our philosophers would not have the cognitive capacity to philosophize about time, nor the scientists would perform experiments. > > Instead, ultimate causes are the physical causes that generate, by >> natural selection, a mind with such concepts and such phenomenology >> that is capable of such reasoning.

Of course the M theory is not a theory of everything, It may be mathematical manifold in which our bodies and the substrate of our minds live. but the world of the mind is different form the phisico-mathematical world. In a timeful way of thinking It can be said that the mind evolved (along time) by natural selection to permit its owm survival and reproduction, but it also can be said that the mind, or our shared minds, made of communicable concepts, make possible the existence of the mathematical substrate in which we live. > > [Our phenomenology conform a common, communicable reality among us >> because it is the product of a common mind, that is a product of a >> common brain architecture, that is a result of a common brain >> development program that is a result of a common genetic >> inheritance] >> > > Let me ask Max Velmans' question again.

Does for example observation happens in the brain The activity of the brain is the mind and the mind is a separate world that includes all that can be perceived. What is outside of the mind may just plain mathematics. What we call phisical world is in reality set of phenomenons perceived by the mind. Observations happen in the mind. We can repeat and verify experiments because we live in the same mathematical reality outside of the mind, and because our minds have similar architecture and experience, so we have the same language, interests, experimental machines, procedures, so, as Eric Voegelin said, we live in a shared social mind. However, The COMP hypothesis it is possible to parsimoniously substitute every component of the brain by a silicon analogue without the mind being aware of the change. this , for me, makes the question "were our minds come from" a mistery > > > An example of ultimate causes may be the theory of Relativity, >> statistical mechanics, the fact that we live in a four dimensional >> universe and our 4d life lines go along a maximum gradient of >> entropy, and the desplacement along these lines is called time, that >> is local to each line.

The M theory describes a timeless manifold, but there are partial phisical laws, that describe particular local phenomenons, that uses time as parameters, but these phisical laws which take time as parameter, do not have a preference for a particular arrow of time, so, as I try to show, heat in the air can rearrange the pieces of a porcelain vase and push it up to the table. causality appears in our time-oriented mind, who proceed, as I try to demonstrate in the presentation, in the computable direction , the direction of entropy increase. for this reason causes are less entropic that consequences. is the drop of the vase what causes his crash because entropy increase is the direction of life and we observe it this way. > Let us say that there is some conglomerate of atoms.

That may be the definition of life too. From inside, they must live in a predictable environment with smooth phisical laws where entrophy dangers and opportinities can be discovered to react appropriately > The same is with causation.

Does it mean something more as solution to some transient > inexorable governing laws? > At the end as I said ultimate causes can be just consequences. I used ultimate causes in the sense of evolutionary psichology, but this does not ultimately bring any definitive meaning of causality, when seen from a broader philosophical perspective. what is interesting is the link between the phisical and the philosophical world, betwen the world of phisico-mathematical and the world of the mind that evolutionary thinking brings. > As for the entropy and the arrow of time, recently I have found some nice > quotes about Boltzmann > > From Boltzmann’s fluctuation hypothesis to Boltzmann’s Brain > http://blog.rudnyi.ru/2012/06/**boltzmanns-brain.html<http://blog.rudnyi.ru/2012/06/boltzmanns-brain.html> > > That's what happens with the entropy approach: > > “And that minimum fluctuation would be “Boltzmann’s Brain.” Out of the > background thermal equilibrium, a fluctuation randomly appears that > collects some degrees of freedom into the form of a conscious brain, with > just enough sensory apparatus to look around and say “Hey!

Boltzman pressuposes, that , since no random arrangement of matter is statistically impossible, and Boltzman demonstrated it in certain conditions (ergodic conditions) , with enough time, some arrangements of matter would simulate minds, or even worlds and civilizations. But 15.000 Million years, that is the age of the universe is not enough. The Boltzman mechanism lies in random events. the process of natural selection instead select random events and create designs more fast. Seen from a mathematical four dimensional perspective,, or better, in what the phisicist call a phase space, adaptations may be seen as attractors in a chaotic evolution. boltzman evolutions are pure chaotic.
