That in the soul which is called the mind is, before it thinks, not actually any real thing.
AristotleIf then nature makes nothing without some end in view, nothing to no purpose, it must be that nature has made all of them for the sake of man.
AristotleThe error of Socrates must be attributed to the false notion of unity from which he starts. Unity there should be, both of the family and of the state, but in some respects only. For there is a point at which a state may attain such a degree of unity as to be no longer a state, or at which, without actually ceasing to exist, it will become an inferior state, like harmony passing into unison, or rhythm which has been reduced to a single foot. The state, as I was saying, is a plurality which should be united and made into a community by education
