Knowledge descries; wisdom applies.

The height of all philosophy is to know thyself; and the end of this knowledge is to know God. Know thyself, that thou mayest know God; and know God, that thou mayest love him and be like him. In the one thou art initiated into wisdom; and in the other perfected in it.

The great comprehensive truths, written in letters of living light on every page of our history, are these: Human happiness has no perfect security but freedom; freedom, none but virtue; virtue, none but knowledge; and neither freedom nor virtue has any vigor or immortal hope except the principles of the Christian faith...

If self-knowledge be a path to virtue, virtue is a much better one to self-knowledge. The more pure the soul becomes, it will, like certain precious stones that are sensible to the contact if poison, shrink from the fetid vapors of evil impressions.

We’re drowning in information and starving for knowledge.

Education as a political weapon could not exist if we respected the rights of children. If we respected the rights of children, we should educate them so as to give them the knowledge and the mental habits required for forming independent opinions; but education as a political institution endeavors to form habits and to circumscribe knowledge in such a way as to make one set of opinions inevitable.

Neither acquiescence in skepticism nor acquiescence in dogma is what education should produce. What it should produce is a belief that knowledge is attainable in a measure, though with difficulty; that much of what passes for knowledge at any given time is likely to be more or less mistaken, but that the mistakes can be rectified by care and industry... Knowledge, like other good things, is difficult, but not impossible; the dogmatist forgets the difficulty, the skeptic denies the possibility. Both are mistaken, and their errors, when widespread, produce social disaster.

Right conduct can never, except by some rare accident, be promoted by ignorance or hindered by knowledge.

Three passions, simple but overwhelmingly strong, have governed my life: the longing for love, the search for knowledge, and unbearable pity for the suffering of mankind... the whole world of loneliness, poverty, and pain make a mockery of what human life should be.

Knowledge of ourselves teaches us whence we come, where we are and whither we are going. We come from God and we are in exile; and it is because our potency of affection tends towards God that we are aware of this state of exile.

Whoever interrupts the conversation of others to make a display of his fund of knowledge, makes notorious his own stock of ignorance.

The shortest and surest way of arriving at real knowledge is to unlearn the lessons we have been taught, to remount the first principles, and take nobody's word about them.

Whatever study tends neither directly nor indirectly to make us better men and citizens is at best but a specious and ingenious sort of idleness, and the knowledge we acquire by it only a creditable kind of ignorance, nothing more.

I grew up among wise man and found that there is nothing better for man than silence. Knowledge is not the main thing, but deeds.

All knowledge is founded upon the coincidence of an objective with a subjective.

The pith of conversation does not consist in exhibiting your own superior knowledge on matters of small importance, but in enlarging, improving, and correcting the information you possess, by the authority of others.

Knowledge alone does not stop men from evil. The poor and the ignorant are not the greatest sinners. Man's mind may unfold, his intellect grow more keen, his understanding more profound, yet side by side with this may be a moral degeneration such as existed in pagan Greece and Rome.

Who shrinks from knowledge of his calamities but aggravates his fear; troubles half seen do torture all the more.

There is no real love of virtue without the knowledge of public good.

To attain excellence in society, an assemblage of qualification is requisite: disciplined intellect, to think clearly, and to clothe thought with propriety and elegance; knowledge of human nature, to suit subject to character; true politeness, to prevent giving pain; a deep sense of morality, to preserve the dignity of speech; and a spirit of benevolence, to neutralize its asperities, and sanctify its powers.
