There are three classes of intellects: one which comprehends by itself; another which appreciates what others comprehend; and a third which neither comprehends by itself nor by the showing of others; the first is the most excellent, the second is good, and the third is useless.
– Niccolò Machiavelli
From his book The Prince. I think that in today’s world, we need more of the first class – those who can think lucidly in the face of noise and chaos; those who can think first for themselves, incubate new ideas in their minds and formulate thought independent of the interference of external influence. They will be the ones who will push the human race forward.
