Assumption
No dichotomy between mind and body/ mind and brain
All mental processes, even the most
complex psychological processes,
derive from operations of the brain.
The central tenet of this view is that
what we commonly call mind is a
range of functions carried out by the
brain. (Kandel, 1998)

attention
Utopia lies at the horizon. When I draw nearer by two steps, it
retreats two steps. If I proceed ten steps forward, it swiftly slips ten
steps ahead. No matter how far I go, I can never reach it. What, then,
is the purpose of utopia? It is to cause us to advance.”
