Knowledge is sometimes superfluous: when we need it, we have it not.
Knowledge is of no value unless you put it into practice.
It is better of course to know useless things than to know nothing.
It is harder to conceal ignorance than to acquire knowledge.
Knowledge is power only if man knows what facts not to bother with.
The one exclusive sign of thorough knowledge is the power of teaching.
Even knowledge has to be in the fashion, and where it is not, it is wise to affect ignorance.
It is better, of course, to know useless things than to know nothing.
There's no learning without trying lots of ideas and failing lots of times.
