Evald Vasilyevich Ilyenkov. The school should learn to think (№ 284366)

But every valid question that grows out of the grounds of life and unsolvable with the help of already established, familiar and clichéd routine methods, formulated always for consciousness as a formally insoluble contradiction.
But more accurately - as "logical" contradiction, insoluble purely logical means - that is, next to purely mechanical, machineoperating operations on previously memorized "concepts" (or more precisely - on the "terms").
Philosophy long ago figured out that the real "question" to be addressed only through further investigation of the facts, always looks like a "logical contradiction", as "paradox".
So exactly where in the structure of knowledge suddenly appears a "contradiction" (some say so, others that way) and only occurs, in fact, the need to investigate the object itself. This is an indicator that the knowledge enshrined in the common provisions are too General, vague, one-sided.
The mind, accustomed to act to stamp a recipe for "standard solutions" and are lost where it is required an independent (creative) solution, it therefore "does not like" contradictions. He tries to crawl to cover, turning again and again trampled, routine track. And when he eventually fails, when the "contradiction" stubbornly recurs again and again, such "intelligence" breaks down in a tantrum - exactly where you need to "think".
That is why the attitude to contradiction and is a very accurate measure of the culture of the mind. Even, in fact, an indicator of its presence.
