Self-love and reason to one end aspire.

Experience keeps a dear school, but fools will learn in no other, an scarcely in that; for it is true, we may give advice, but we cannot give conduct. Remember this; they that will not be counseled cannot be helped. If you do not hear reason she will rap you over your knuckles.

If Passion drives, let Reason hold the Reins.

They that will not be counseled, cannot be helped. If you do not hear reason she will rap you on the knuckles.

Our best hope for the future is that the intellect - the scientific spirit, reason - should in time establish a dictatorship over the human mind. The very nature of reason is a guarantee that it would not fail to concede to human emotions, and to all that is determined by them, the position to which they are entitled. But the common pressure exercised by such a domination of reason would prove to be the strongest unifying force among men, and would prepare the way for further unifications. Whatever, like the ban laid upon thought by religion, opposes such a development is a danger for the future of mankind.

The reason for so much bad science is not that talent is rare - not at all. What is rare is character.

The individual who needs a reason for being moral which is not itself a moral reason cannot have it. There is nothing surprising about this; it would be much more surprising if such reasons could be found. For it is more than apparently paradoxical to suppose that considerations of advantage could ever of themselves justify accepting a real disadvantage.

The habit of virtue cannot be formed in the closet; good habits are formed by acts of reason in a persevering struggle with temptation.

One great reason why men practice generosity so little in the world is their finding so little there. Generosity is catching; and if so many men escape it, it is in a great degree from the same reason the countrymen escape the smallpox, because they meet no one to give it to them.

God’s love is the reason for our creation, a free, gratuitous love, a love without limits... Our duty is to translate this love into acts of solidarity and commitment.

It is much easier to think right without doing right, than to do right without thinking right. Just thoughts may, and often do, fail of producing just deeds; but just deeds are sure to get just thoughts. The clearest understanding can do little in purifying an impure heart, the strongest little in straightening a crooked one. You cannot reason or talk an Augean stable into cleanliness. A single day's work would make more progress in such a task than a century's words.

He who fears to venture as far as his heart urges and his reason permits, is a coward; he who ventures further than he intended to go, is a slave.

We are all tatooed in our cradles with the beliefs of our tribe; the record may seem superficial, but it is indelible. You cannot educate a man wholly out of the superstitious fears which were implanted in his imagination, no matter how utterly his reason may reject them.

The contradiction between what is requested of man and what can be offered to him has become so striking, the ideology so thin, the discontents in civilization so great that they must be compensated through annihilation of those who do not conform, political enemies, Jews, asocial persons, the insane. The new order of fascism is reason revealing itself as unreason.

Disbelief in futurity loosens in a great measure the ties of morality, and may be for that reason pernicious to the peace of civil society.

Morals excite passions, and produce or prevent actions. Reason of itself is utterly impotent in this particular. The rules of morality, therefore, are not conclusions of our reason.

Nothing can oppose or retard the impulse of passion... Reason is, and ought only to be the slave of the passions, and can never pretend to any other office than to serve and obey them.

Our perceptions and our understanding are directed, in large measure, by our will. We are aware of, and we think about, the things which, for one reason or another, we want to see and understand. Where there’s a will there is always an intellectual way. The capacities of the human mind are almost indefinitely great.

The end cannot justify the means, for the simple and obvious reason that the means employed determine the nature of the ends produced.

What we do depends in large measure upon what we think, and if what we do it evil, there is good empirical reason for supposing that our thought patterns are inadequate to material, mental or spiritual reality.
