The man who lives free from folly is not so wise as he thinks. The mind cannot long act the role of the heart. The most trying fools are the bright ones. Not all those who know their minds know their hearts as well. It is often merely for an excuse that we say things are impossible.
Nothing is so contagious as an example.
We never do great good or evil without bringing about more of the same on the part of others. Old men love to give advice to console themselves for not being able to set a bad example. One who finds no satisfaction in himself seeks for it in vain elsewhere. Our virtues are most often but our vices disguised. Perfect virtue is to do unwitnessed that which we should be capable of doing before all the world.
