Nature without learning is like a blind man; learning without Nature, like a maimed one; practice without both, incomplete. As in agriculture a good soil is first sought for, then a skilful husbandman, and then good seed; in the same way nature corresponds to the soil, the teacher to the husbandman, precepts and instruction to the seed.
PlutarchSince, during storms, flames leap from the humid vapors and dark clouds emit deafening noises, is it surprising the lightning, when it strikes the ground, gives rise to truffles, which do not resemble plants?
PlutarchIf you hate your enemies, you will contract such a vicious habit of mind that it will break out upon those who are your friends, or those who are indifferent to you.
PlutarchWhen a man's eyes are sore his friends do not let him finger them, however much he wishes to, nor do they themselves touch the inflammation: But a man sunk in grief suffers every chance comer to stir and augment his affliction like a running sore; and by reason of the fingering and consequent irritation it hardens into a serious and intractable evil.
PlutarchA human body in no way resembles those that were born for ravenousness; it hath no hawk's bill, no sharp talon, no roughness of teeth, no such strength of stomach or heat of digestion, as can be sufficient to convert or alter such heavy and fleshy fare . . . There is nobody that is willing to eat even a lifeless and a dead thing even as it is; so they boil it, and roast it, and alter it by fire and medicines, as it were, changing and quenching the slaughtered gore with thousands of sweet sauces, that the palate being thereby deceived may admit of such uncouth fare.
