Aphorisms, except they should be ridiculous, cannot be made but of the pith and heart of sciences; for discourse of illustration is cut off; recitals of examples are cut off; discourse of connection and order is cut off; descriptions of practice are cut off. So there remaineth nothing to fill the aphorisms but some good quantity of observation; and therefore no man can suffice, nor in reason will attempt, to write aphorisms, but he that is sound and grounded.

Rude am I in my speech, And little blessed with the soft phrase of peace; For since these arms of mine had seven years' pith, Till now some nine moons wasted, they have us'd Their dearest action in the tented field, And little of this great world can I speak, More than pertains to feats of broil and battle, And therefore little shall I grace my cause In speaking for myself.william shakespeare
