The greatness of common sense, and its title to reverence, appear in this, that it deals with vast complexity, that is, with the innumerable elements of a situation. Common sense discerns and judges a path through this knotted and tangled maze.

An enemy will train us in watchfulness; for if he be wary to seize on every error and trip us, we shall be more heedful to expose nothing, and this will drive us to prudence and thoughtfulness.

As anger is a passing storm, so it comes not gradually and with signs, but like a sudden sweep of wind or black squall.

Now, if we understand what unlucky persons are, we shall see that they are to be shunned, or that we are to consort with them only out of kindness or from sympathy, but without joining our interests with theirs; for they are persons who are not harmonious with the condition of things around them, and are as much at issue with life as a bird who should try to live in the water, or a fish to float in the air.
