You can't show me any behavior of the brain that is not a reflexive reaction.
But coherent thoughts cannot be put together by a reflex.
The thing that has a thought knows it is having the thought and it has that thought within the milieu of a lifetime of experiences.
Wrong. Well with you that's not true since you can't be shown anything.
Wrong again. At the simplest level all coherent thought is the product of neuron work which is entirely reflexive, dependent on mechanics of nerve conduction. However this is not reflex in the classical sense of knee jerk ideas.
Most things going on in the brain are complex with interactions up and down tracts, across tracts, and among tracts. Almost no attending or awereness related nervous activity is reflex activity. If, in the seventies if you you had read operant and respondent conditioning material (
Operant conditioning Classical conditioning you'd have actually learned something about behavior. Of course one needs to also study relevant sensory and learning neuroscience to understand how the brain gets it done.
