AT thy first encounter with anyone, say presently to thyself; This man, what are his opinions concerning that which is good or evil? as concerning pain, pleasure, and the causes of both; concerning honour, and dishonour, concerning life and death; thus and thus. Now if it be no wonder that a man should have such and such opinions, how can it be a wonder that he should do such and such things? I will remember then, that he cannot but do as he doth holding those opinions that he doth. Remember, that as it is a shame for any man to wonder that a figtree should bear figs, so also to wonder that the World should bear anything, whatsoever it is which in the ordinary course of nature it may bear. To a physician also and to a pilot it is a shame either for the one to wonder, that such and such a one should have an ague; or for the other, that the winds should prove contrary.
