“There is nothing that comes closer to true humility than the intelligence. It is impossible to feel pride in one's intelligence at the moment when one really and truly exercises it.”

Review of A Coat of Many Colours: Occasional Essays by Herbert Read, Poetry Quarterly (Winter 1945)
Context: Each generation imagines itself to be more intelligent than the one that went before it, and wiser than the one that comes after it. This is an illusion, and one should recognise it as such, but one ought also to stick to one's own world-view, even at the price of seeming old-fashioned: for that world-view springs out of experiences that the younger generation has not had, and to abandon it is to kill one's intellectual roots.

Context: You asked for wisdom? Hear these words. Nothing limits intelligence more than ignorance; nothing fosters ignorance more than one's own opinions; nothing strengthens opinions more than refusing to look at reality.
