For just as poets love their own works, and fathers their own children, in the same way those who have created a fortune value their money, not merely for its uses, like other persons, but because it is their own production. This makes them moreover disagreeable companions, because they will praise nothing but riches.
PlatoThe choice of souls was in most cases based on their own experience of a previous life... Knowledge easily acquired is that which the enduing self had in an earlier life, so that it flows back easily.
Plato
