I can well conceive a man without hands, feet, head. But I cannot conceive man without thought; he would be a stone or a brute.

Reason commands us far more imperiously than a master; for in disobeying the one we are unfortunate, and in disobeying the other we are fools.

Human beings must be known to be loved; but Divine beings must be loved to be known.

Habit is a second nature that destroys the first. But what is nature? Why is habit not natural? I am very much afraid that nature itself is only a first habit, just as habit is a second nature.

If our condition were truly happy, we would not seek diversion from it in order to make ourselves happy.

In each action we must look beyond the action at our past, present, and future state, and at others whom it affects, and see the relations of all those things. And then we shall be very cautious.

Man is but a reed, the most feeble thing in nature, but he is a thinking reed.

We never love a person, but only qualities.

Custom is our nature. What are our natural principles but principles of custom?

The consciousness of the falsity of present pleasures, and the ignorance of the vanity of absent pleasures, cause inconstancy.

Jesus is the God whom we can approach without pride and before whom we can humble ourselves without despair.

Truth is so obscure in these times, and falsehood so established, that, unless we love the truth, we cannot know it.

To have no time for philosophy is to be a true philosopher.

People are usually more convinced by reasons they discovered themselves than by those found by others.

The last proceeding of reason is to recognize that there is an infinity of things which are beyond it. There is nothing so conformable to reason as this disavowal of reason.

Men never do evil so completely and cheerfully as when they do it from religious conviction.

It is good to be tired and wearied by the futile search after the true good, that we may stretch out our arms to the Redeemer.

Atheism shows strength of mind, but only to a certain degree.

We conceal it from ourselves in vain – we must always love something. In those matters seemingly removed from love, the feeling is secretly to be found, and man cannot possibly live for a moment without it.

In faith there is enough light for those who want to believe and enough shadows to blind those who don’t.

There are some who speak well and write badly. For the place and the audience warm them, and draw from their minds more than they think of without that warmth.

Faith is different from proof; the latter is human, the former is a Gift from God.

Vanity is but the surface.

The last act is bloody, however pleasant all the rest of the play is: a little earth is thrown at last upon our head, and that is the end forever.

When we are in love we seem to ourselves quite different from what we were before.

Contradiction is not a sign of falsity, nor the lack of contradiction a sign of truth.

Few friendships would survive if each one knew what his friend says of him behind his back.

Justice is what is established; and thus all our established laws will necessarily be regarded as just without examination, since they are established.

Our soul is cast into a body, where it finds number, time, dimension. Thereupon it reasons, and calls this nature necessity, and can believe nothing else.

Kind words do not cost much. Yet they accomplish much.

Words differently arranged have a different meaning, and meanings differently arranged have different effects.

Desire and force between them are responsible for all our actions; desire causes our voluntary acts, force our involuntary.

Men blaspheme what they do not know.

The only shame is to have none.

We run carelessly to the precipice, after we have put something before us to prevent us seeing it.

Nothing is as approved as mediocrity, the majority has established it and it fixes it fangs on whatever gets beyond it either way.

The supreme function of reason is to show man that some things are beyond reason.

Belief is a wise wager. Granted that faith cannot be proved, what harm will come to you if you gamble on its truth and it proves false? If you gain, you gain all; if you lose, you lose nothing. Wager, then, without hesitation, that He exists.

Vanity of science. Knowledge of physical science will not console me for ignorance of morality in time of affliction, but knowledge of morality will always console me for ignorance of physical science.

Law, without force, is impotent.

We are only falsehood, duplicity, contradiction; we both conceal and disguise ourselves from ourselves.

Men despise religion. They hate it and are afraid it may be true.

Thus so wretched is man that he would weary even without any cause for weariness… and so frivolous is he that, though full of a thousand reasons for weariness, the least thing, such as playing billiards or hitting a ball, is sufficient enough to amuse him.

The greatness of man is great in that he knows himself to be wretched. A tree does not know itself to be wretched.

I have discovered that all human evil comes from this, man’s being unable to sit still in a room.

The heart has its reasons of which reason knows nothing.

The immortality of the soul is a matter which is of so great consequence to us and which touches us so profoundly that we must have lost all feeling to be indifferent about it.

If we must not act save on a certainty, we ought not to act on religion, for it is not certain. But how many things we do on an uncertainty, sea voyages, battles!

The strength of a man’s virtue should not be measured by his special exertions, but by his habitual acts.

Nothing gives rest but the sincere search for truth.

The eternal silence of these infinite spaces frightens me.

The struggle alone pleases us, not the victory.

Imagination disposes of everything; it creates beauty, justice, and happiness, which are everything in this world.

Between us and heaven or hell there is only life, which is the frailest thing in the world.

Faith embraces many truths which seem to contradict each other.

Small minds are concerned with the extraordinary, great minds with the ordinary.

Earnestness is enthusiasm tempered by reason.

Men are so necessarily mad, that not to be mad would amount to another form of madness.

The sensitivity of men to small matters, and their indifference to great ones, indicates a strange inversion.

Men often take their imagination for their heart; and they believe they are converted as soon as they think of being converted.

Do you wish people to think well of you? Don’t speak well of yourself.

Nothing fortifies scepticism more than the fact that there are some who are not sceptics; if all were so, they would be wrong.

It is natural for the mind to believe and for the will to love; so that, for want of true objects, they must attach themselves to false.

Eloquence is a painting of the thoughts.

Man’s greatness lies in his power of thought.

Faith certainly tells us what the senses do not, but not the contrary of what they see; it is above, not against them.

Even those who write against fame wish for the fame of having written well, and those who read their works desire the fame of having read them.

We only consult the ear because the heart is wanting.

If man made himself the first object of study, he would see how incapable he is of going further. How can a part know the whole?

Imagination decides everything.

There are two kinds of people one can call reasonable: those who serve God with all their heart because they know him, and those who seek him with all their heart because they do not know him.

The weather and my mood have little connection. I have my foggy and my fine days within me; my prosperity or misfortune has little to do with the matter.

Justice without force is powerless; force without justice is tyrannical.

That we must love one God only is a thing so evident that it does not require miracles to prove it.

Concupiscence and force are the source of all our actions; concupiscence causes voluntary actions, force involuntary ones.

Evil is easy, and has infinite forms.

He that takes truth for his guide, and duty for his end, may safely trust to God’s providence to lead him aright.
