The wisest man may be a blind father.

Man, a mere inhabitant of the earth, cannot overstep its boundaries! But though he is confined to its crust, he may penetrate into all its secrets.

Whatever one man is capable of conceiving, other men will be able to achieve

In presence of Nature's grand convulsions, man is powerless.

However strong, however imposing a ship may appear, it is not 'disgraced' because it flies before the tempest. A commander ought always to remember that a man's life is worth more than the mere satisfaction of his own pride. In any case, to be obstinate is blameable, and to be wilful is dangerous.
