Hi again

Right

Consicence may be a less sophisticated version of
self-consciousness.. I think honestly that all attemps of explaining
conscience in terms of a certain degree of complexity or as a certain
property of neurons or tissues goes the wrong path. Broadly speaking,
this is like a medieval scientist trying to explain  a video game
console in terms of the complexity and colourfulness of the printed
circuits. These views ignores the work of the hardware designer that
creates the machine and the programmer that make the algorithms.

In living beings the work of the hardware designer and the
programmer are done by a guy called Natural Selection. and this guy
builds things for a purpose: Survival. What is conscience for? A self
preserving being  with a central nervous system (an animal) must
stablish a clear distinction between its body and the environment in
order to preserve itself.  If he do not know the status of each of
its parts in relation to the environment, he can not determine the
priorities for self preservation: does he must avoid a predator? does
he must eat something? etc. The effect of the activity set of all
these central nervous systems is the conscience in the most basic
manifestation.

No degree of "complexity" or neuronal-like machinery will manifest
conscience without the proper  algorithms (and the sensors-actuators
too). As Theodosius Dobzhansky said: Nothing in Biology (and i
suspect, nothing in anything) Makes Sense Except in the Light of
Evolution.

Honestly: Alberto.

In the book of Jeffrey Gray, "Consciousness: Creeping up on the hard problem" the evolution viewpoint is played well out. Well, he consider consciousness as conscious experience, so it is not conscience.

First, in his view, this is the exactly the argument for causality of consciousness. Second his argument is that roughly speaking conscious experience plays a role of late-error correction that happens to be working more efficiently as compared with unconscious feedback mechanisms.
