Consciousness: Preparation to Action



This is a continuation of the post Picasso and his Model: Feelings.

Henri Bergson summarises his view on consciousness exposed in Matter and Memory as follows : 
  • The idea that we have disengaged from the facts and confirmed by reasoning is that our body is an instrument of action, and of action only. 
  • In no degree, in no sense, under no aspect, does it serve to prepare, far less to explain, a representation. 
  • Consider external perception: there is only a difference of degree, not of kind, between the so-called perceptive faculties of the brain and the reflex functions of the spinal cord. 
  • While the spinal cord trans­forms the excitations received into movements which are more or less necessarily executed, the brain puts them into relation with motor mechanisms which are more or less freely chosen; but that which the brain explains in our perception is action begun, pre­pared or suggested, it is not perception itself. 
  • Consider memory. The body retains motor habits capable of acting the past over again; it can resume attitudes in which the past will insert itself; or, again, by the repetition of certain cerebral phenomena, which have pro­longed former perceptions, it can furnish to remembrance a point of attachment with the actual, a means of recovering its lost influ­ence upon present reality: but in no case can the brain store up recollections or images. 
  • Thus, neither in perception, nor in memory, nor a fortiori in the higher attainments of mind, does the body contribute directly to representation. 
  • By developing this hypoth­esis under its manifold aspects and thus pushing dualism to an extreme, we appeared to divide body and soul by an impassable abyss. In truth, we were indicating the only possible means of bringing them together.
  • All the difficulties raised by this problem, either in ordinary dualism, or in materialism and idealism, come from considering, in the phenomena of perception and memory, the physical and the mental as duplicates of one another.
Bergson thus refutes one of the ideas expressed in the post of mental models of the physical world naturally connecting to mathematical models of the physical world.  

But the other idea in the post is in line with Bergson's view of the importance of feelings to guide actions as responses to the world supporting intuition and transforming intellectual deliberation into lived experience. 

Both aspects connect to AI viewed to offer mathematical models of the world while lacking feelings, which is not at all in line with Bergson's view on consciousness or Human Intelligence HI. 

Bergson points to limitations of mathematical models of his time as static and unable to capture the complexity of the world. Today mathematics + computer offers a very rich world of dynamic simulations expanding reality to virtual reality, while human consciousness remains the same.  

Notice that Bergson connects matter to memory instead of body to soul, thus emphasising memory. 

Bergson offers some hope that HI will continue to have a role.
