Shun no toil to make yourself remarkable by some talent or other; yet do not devote yourself to one branch exclusively. Strive to get clear notions about all. Give up no science entirely; for science is but one.Lucius Annaeus Seneca
Bad company is as instructive as licentiousness. One makes up for the loss of one's innocence with the loss of one's prejudices.Denis Diderot
Our observation of nature must be diligent, our reflection profound, and our experiments exact. We rarely see these three means combined; and for this reason, creative geniuses are not common.Denis Diderot
