You need to know enough philosophy so that the methods of logical analysis are available to you to be used as a tool. One of the most depressing thin… - John Searle

You need to know at least one foreign language well enough so that you can read the best literature that that language has produced in the original, and so you carry on a reasonable conversation and have dreams in that language. There are several reasons why this is crucial, but the most important is perhaps this: you can never understand one language until you understand at least two.

Materialism ends up denying the existence of any irreducible subjective qualitative states of sentience or awareness.

One can imagine a computer simulation of the action of peptides in the hypothalamus that is accurate down to the last synapse. But equally one can imagine a computer simulation of the oxidation of hydrocarbons in a car engine or the action of digestive processes in a stomach when it is digesting pizza. And the simulation is no more the real thing in the case of the brain than it is in the case of the car or the stomach. Barring miracles, you could not run your car by doing a computer simulation of the oxidation of gasoline, and you could not digest pizza by running the program that simulates such digestion. It seems obvious that a simulation of cognition will similarly not produce the effects of the neurobiology of cognition.
