The human personality contains nothing which may not, in the twinkling of an eye, become altogether changed--nothing in which, before you can look round, there may not spring to birth some cankerous worm which is destined to suck thence the essential juice.

Yes, it is a common thing to see not only an overmastering passion, but also a passion of the most petty order, arise in a man who was born to better things, and lead him both to forget his greatest and most sacred obligations, and to see only in the veriest trifles the Great and the Holy.

For human passions are as numberless as is the sand of the seashore, and go on to become his most insistent of masters.

Happy, therefore, the man who may choose from among the gamut of human passions one which is noble! Hour by hour will that instinct grow and multiply in its measureless beneficence; hour by hour will it sink deeper and deeper into the infinite paradise of his soul.

But there are passions of which a man cannot rid himself, seeing that they are born with him at his birth, and he has no power to abjure them.
