Well thought (!) Terry.
You might be surprised (or maybe not) how far I share your analysis even though I do not share your conclusion. My view, simply put for once, is that there is a time to think and there is a time to drop thinking; both are real, both are human, as much as human wake and sleep are. Furthermore, I submit that one is not possible (or, would not be what it is) without the other. Language, logic, and henceforth thought implies departing from the immediate, unseparated, overwhelming "real" so as to deal with it through the artificial mediation of symbols. One type of relationship with reality implies switching off the other. They simply cannot exist simultaneously. So I friendly disagree with you and JamesThomas when you both (symmetrically of course) suggest that one is good and the other is bad. I think you are wrong when you say:
Thinking is man's only basic virtue. On the other hand, the source of all of man's evils is the act of blanking out. This is the deliberate failure to pay attention to what is real in all its detail while substituting what one wishes was real in its place and then basing decisions on the falsereality.
The nazi socio-political machinery, for instance, worked as it did with thousands of "thinking" people focusing on the detail of their task in a very binary logical manner, each of them being unable to "zoom out" and perceive the absurdity and horror of the overall structure. But it was helped, perhaps, by the incapacity of the few "dreamers" who did "zoom out" and see, to "zoom in" again into effective thoughtful action.
We haven't learn to breathe in and out of "thinking," except in a collective and tragic way, where some play "reason" and others play "irrational," with oversimplification on both parts and much suffering.
