In all societies, it is advisable to associate if possible with the highest; not that the highest are always the best, but because, if disgusted there, we can descend at any time; but if we begin with the lowest, to ascend is impossible.

The highest knowledge can be nothing more than the shortest and clearest road to truth; all the rest is pretension, not performance, mere verbiage and grandiloquence, from which we can learn nothing.

It is a curious paradox that precisely in proportion to our own intellectual weakness will be our credulity, to those mysterious powers assumed by others; and in those regions of darkness and ignorance where man cannot effect even those things that are within the power of man, there we shall ever find that a blind belief in feats that are far beyond those powers has taken the deepest root in the minds of the deceived, and produced the richest harvest to the knavery of the deceiver.

Idleness is the grand Pacific Ocean of life, and in that stagnant abyss the most salutary things produce no good, the most noxious no evil. Vice, indeed, abstractedly considered, may be, and often is engendered in idleness; but the moment it becomes efficiently vice, it must quit its cradle and cease to be idle.

Criticism is like champagne, nothing more execrable if bad, nothing more excellent if good; if meagre, muddy, vapid and sour, both are fit only to engender colic and wind; but if rich, generous and sparkling, they communicate a genial glow to the spirits, improve the taste, and expand the heart.

The true measure of your character is what you do when nobody's watching.

He that has never suffered extreme adversity knows not the full extent of his own depravation.
