“All knowledge is interconnected. To cut off a single field — any field — from the rest of cognition is to drop the vast context which makes that field possible and which anchors it to reality. The ultimate result, as with any failure of integration, is floating abstractions and self-contradiction.”
— Leonard Peikoff, “O.P.A.R.”, page 127.
(The Hindenburg disaster. This is just a visual metaphor for a floating abstraction: when the context is dropped and reality sets in, concepts become a dangerous thing.)
Earlier when I talked about epistemological evasion I mentioned our mental laziness, how we avoid the effort to think correctly because it hurts. The problem is that if we really go through each idea thoroughly, we become responsible for it when we use it, and that is something we hate. This may sound offensive, but I have no doubt that this is the case with the vast majority of us, during the vast majority of our waking time. Of course, I include myself in this team of evaders.
