Learning is a good medicine: but no medicine is powerful enough to preserve itself from taint and corruption independently of defects in the jar that it is kept in. One man sees clearly but does not see straight: consequently he sees what is good but fails to follow it; he sees knowledge and does not use it.

Teach him a certain refinement in sorting out and selecting his arguments, with an affection for relevance and so for brevity. Above all let him be taught to throw down his arms and surrender to truth as soon as he perceives it, whether the truth is born at his rival's doing or within himself from some change in his ideas.

The first lessons with which we should irrigate his mind should be those which teach him to know himself, and to know how to die ... and to live.

Any time and any place can be used to study: his room, a garden, is table, his bed; when alone or in company; morning and evening. His chief study will be Philosophy, that Former of good judgement and character who is privileged to be concerned with everything.

I would like to suggest that our minds are swamped by too much study and by too much matter just as plants are swamped by too much water or lamps by too much oil; that our minds, held fast and encumbered by so many diverse preoccupations, may well lose the means of struggling free, remaining bowed and bent under the load; except that it is quite otherwise: the more our souls are filled, the more they expand; examples drawn from far-off times show, on the contrary, that great soldiers ad statesmen were also great scholars.

Their pupils and their little charges are not nourished and fed by what they learn: the learning is passed from hand to hand with only one end in view: to show it off, to put into our accounts to entertain others with it, as though it were merely counters, useful for totting up and producing statements, but having no other use or currency. 'Apud alios loqui didicerunt, non ipsi secum' [They have learned how to talk with others, not with themselves]

And I loathe people who find it harder to put up with a gown askew than with a soul askew and who judge a man by his bow, his bearing and his boots.

Socrates and then Archesilaus used to make their pupils speak first; they spoke afterwards. 'Obest plerumque iss discere volunt authoritas eorum qui docent.' [For those who want to learn, the obstacle can often be the authority of those who teach]
