The instruction of children should aim gradually to combine knowing and doing. Among all sciences mathematics seems to be the only one of a kind to satisfy this aim most completely.
Actual knowledge is identical with its object: in the individual, potential knowledge is in time prior to actual knowledge, but in the universe as a whole it is not prior even in time. Mind is not at one time knowing and at another not. When mind is set free from its present conditions it appears as just what it is and nothing more: this alone is immortal and eternal (we do not, however, remember its former activity because, while mind in this sense is impassible, mind as passive is destructible), and without it nothing thinks.
It is not a mistake to commit a mistake, for no one commits a mistake knowing it to be one. But it is a mistake not to correct the mistake after knowing it to be one.

You only have to be able to evaluate companies within your circle of competence. The size of that circle is not very important; knowing its boundaries, however, is vital.
We lawyers are always curious, always inquisitive, always picking up odds and ends for our patchwork minds, since there is no knowing when and where they may fit into some corner.
Find out for yourself what are the possesions and ideals that you do not desire. By knowing what you do not want, by elimination, you will unburden the mind, and only then will it understand the essential which is ever there.
