Incredulity is not wisdom, but the worst kind of folly. It is folly, because it causes ignorance and mistake, with all the consequents of these; and it is very bad, as being accompanied with disingenuity, obstinacy, rudeness, uncharitableness, and the like, bad dispositions; from which credulity itself, the other extreme sort of folly, is exempt.
If you are pained by external things, it is not they that disturb you, but your own judgment of them. And it is in your power to wipe out that judgment now.
Of human life the time is a point, and the substance is in a flux, and the perception dull, and the composition of the whole body subject to putrefaction, and the soul a whirl, and fortune hard to divine, and fame a thing devoid of judgment. And, to say all in a word, everything which belongs to the body is a stream, and what belongs to the soul is a dream and a vapor, and life is a warfare and a stranger’s sojourn, and after-fame is oblivion.
Profound ignorance makes a man dogmatic. The man who knows nothing thinks he is teaching others what he has just learned himself; the man who knows a great deal can't imagine that what he is saying is not common knowledge, and speaks indifferently.
Your greatness is measured by your kindness - Your education and intellect by your modesty - Your ignorance is betrayed by your suspicions and prejudices - Your real caliber is measured by the consideration and tolerance you have for others.
The confirmed prejudices of a thoughtful life are as hard to change as the confirmed habits of an indolent life; and as some must trifle away age because they trifled away youth, others must labor on in a maze of error because they have wandered there too long to find their way out.
The trouble of the many and various aims of mortal men bring them much care, and herein they go forward by different paths but strive to reach one end, which is happiness. And that good is that, to which if any man attain, he can desire nothing further... Happiness is a state which is made perfect by the union of all good things. This end all men seek to reach, as I said, though by different paths. For there is implanted by nature in the minds of men a desire for the true good; but error leads them astray towards false goods by wrong paths.
Discourtesy does not spring merely from one bad quality, but from several - from foolish vanity, from ignorance of what is due to others, from indolence, from stupidity, from the distraction of thought, from contempt of others, from jealousy.
A modern commentator made the observation that there re those who seek knowledge about everything and understand nothing. It is wonder - not mere curiosity - a sense of enchantment, of respect for the mysteries of love for the other, that is essential to the difference between a knowing that is simply a gathering of information and techniques and a knowing that seeks insight and understanding. It is wonder that reveals how intimate is the relationship between knowledge of the other and knowledge of the self, between inwardness and outwardness.
