Determinism, Randomness, and the Mind

Determinism, Randomness, and Free Will
It seems to me that if brain-function is random, then its product, reason, cannot be relied upon at all.
Lavengro
J'C: "Random with sophisticated feedback can produce quite meaningful results. Think random error in gene duplication with the feedback of selection and one gets a meaningful result of a new successful species, or a meaningful result of a lethal mutation.

I think cause and effect have very little to do with mind/brain function. Essentially the sensory stimulus is random or at least so voluminous that the first cut by the mind can be thought of as eliminating data points that do not conform to an existing pattern in the nerve cells feeding data to the brain, in other words eliminating worthless random stimuli. Apparently the first cut in the retina is an edge. The first feedback loop is that an edge might be useful and the brain 'requests' data from around the edge. If the data around the edge form the capital 'I' the mind says 'Pay attention this is critical data!' Another feedback loop may say forget it it is just a bridge girder, and the mind moves on, and the cause bridge girder resembling an 'I' has no lasting effect.

The important functions of the brain/mind are these feedback loops that correlate fresh input with existing data to reinforce or weaken the data points. Trying to identify cause and effect is an endless chase through the feedback loops unless one reasonably shortstops the process as the mind does and says this stimulus reproducibly is associated with this response and is a cause and effect relationship."

I just began reading the new book "The Mind's I: Fantasies and Reflections on Self and Soul" by Douglas Hofstadter and Daniel Dennett. See Page 48 for a short discussion of random choices.
