Those who deny the first principle should be flogged or burned until they admit that it is not the same thing to be burned and not burned, or whipped and not whipped.

An ignorant doctor is the aide-de-camp of death.

God, the supreme being, is neither circumscribed by space, nor touched by time; he cannot be found in a particular direction, and his essence cannot change. The secret conversation is thus entirely spiritual; it is a direct encounter between God and the soul, abstracted from all material constraints.

Do not blame Caesar, blame the people of Rome who have so enthusiastically acclaimed and adored him and rejoiced in their loss of freedom and danced in his path and gave him triumphal processions. Blame the people who hail him when he speaks in the Forum of the 'new, wonderful good society' which shall now be Rome, interpreted to mean 'more money, more ease, more security, more living fatly at the expense of the industrious.

Times are bad. Children no longer obey their parents, and everyone is writing a book.

Study carefully, the character of the one you recommend, lest their misconduct bring you shame.

Force overcome by force.

After death the sensation is either pleasant or there is none at all. But this should be thought on from our youth up, so that we may be indifferent to death, and without this thought no one can be in a tranquil state of mind. For it is certain that we must die, and, for aught we know, this very day. Therefore, since death threatens every hour, how can he who fears it have any steadfastness of soul?

If you have a garden and a library, you have everything you need.

How long will men dare to call anything expedient that is not right? Can odium and infamy be of service to any empire, which ought to be supported by glory and by the good-will of its allies? I was often at variance even with my friend Cato. He seemed to me to guard the treasury and the revenues too obstinately, to refuse everything to the farmers of the revenue, and many things to our allies; while we ought to be generous to our allies, and to deal with the farmers of the revenue as leniently as we individually do with our own tenants, especially as the union of orders to which such a course would conduce is for the well-being of the state.

I am a Roman citizen.

We should never take pleasure in causing pain to others, even to those who have wronged us, but rather strive to do good to all.

What! You would convict me from my own words, and bring against me what I had said or written elsewhere. You may act in that manner with those who dispute by established rules. We live from hand to mouth, and say anything that strikes our mind with probability, so that we are the only people who are really at liberty.

I will speak in a low voice, just so as to let the judges hear me. For men are not wanting who would be glad to excite that people against me and against every eminent man; and I will not assist them and enable them to do so more easily.

They are such fools that they seem to expect that, though the Republic is lost, their fish-ponds will be safe.

We know, that of all living beings man is the best formed, and, as the gods belong to this number, they must have a human form. ... I do not mean to say that the gods have body and blood in them; but I say that they seem as if they had bodies with blood in them. . . , Epicurus, for whom hidden things were as tangible as if he had touched them with his finger, teaches us that gods are not generally visible, but that they are intelligible; that they are not bodies having a certain solidity . . . but that we can recognize them by their passing images; that as there are atoms enough in the infinite space to produce such images, these are produced before us . . . and make us realize what are these happy, immortal beings.

I have always been of the opinion that infamy earned by doing what is right is not infamy at all, but glory.

since our leading men think themselves in a seventh heaven, if there are bearded mullets in their fish-ponds that will come to hand for food, and neglect everything else, do not you think that I am doing no mean service if I secure that those who have the power, should not have the will, to do any harm?

The first duty of a man is the seeking after and the investigation of truth.

And what can be more divine than the exhalations of the earth, which affect the human soul so as to enable her to predict the future ? And could the hand of time evaporate such a virtue? Do you suppose you are talking of some kind of wine or salted meat ?

O immortal gods! Men do not realize how great a revenue parsimony can be!

The greatest states have been overthrown by the young and sustained and restored by the old. ... Rashness is the product of the budding-time of youth, prudence of the harvest-time of age.

Anything done against faith or conscience is sinful.

Truth is the ultimate end of the whole universe.

Suppose a person entering a house were to feel heat on the porch, and going further, were to feel the heat increasing, the more they penetrated within. Doubtless, such a person would believe there was a fire in the house, even though they did not see the fire that must be causing all this heat. A similar thing will happen to anyone who considers this world in detail: one will observe that all things are arranged according to their degrees of beauty and excellence, and that the nearer they are to God, the more beautiful and better they are.

The order of authority derives from God, as the Apostle says [in Romans 13:1-7]. For this reason, the duty of obedience is, for the Christian, a consequence of this derivation of authority from God, and ceases when that ceases. But, as we have already said, authority may fail to derive from God for two reasons: either because of the way in which authority has been obtained, or in consequence of the use which is made of it. There are two ways in which the first may occur. Either because of a defect in the person, if he is unworthy; or because of some defect in the way itself by which power was acquired, if, for example, through violence, or simony or some other illegal method.

Now what has been said about the Jews is also to be understood about Cahorsins, and anyone else depending upon the depravity of usury.

Reason in man is rather like God in the world.

For creation is not a change, but that dependence of the created existence on the principle from which it is instituted, and thus is of the genus of relation; whence nothing prohibits it being in the created as in the subject. Creation is thus said to be a kind of change, according to the way of understanding, insofar as our intellect accepts one and the same thing as not existing before and afterwards existing.

Now, as the Word of God is the Son of God, so the love of God is the Holy Spirit.

With regard to the abuse of authority, this also may come about in two ways. First, when what is ordered by an authority is opposed to the object for which that authority was constituted (if, for example, some sinful action is commanded or one which is contrary to virtue, when it is precisely for the protection and fostering of virtue that authority is instituted). In such a case, not only is there no obligation to obey the authority, but one is obliged to disobey it, as did the holy martyrs who suffered death rather than obey the impious commands of tyrants. Secondly, when those who bear such authority command things which exceed the competence of such authority; as, for example, when a master demands payment from a servant which the latter is not bound to make, and other similar cases. In this instance the subject is free to obey or disobey.

It is on account neither of God's weakness nor ignorance that evil comes into the world, but rather it is due to the order of his wisdom and the greatness of his goodness that diverse grades of goodness occur in things, many of which would be lacking if no evil were permitted. Indeed, the good of patience would not exist without the evil of persecution; nor the good of preservation of life in a lion if not for the evil of the destruction of the animals on which it lives.

Charity, by which God and neighbor are loved, is the most perfect friendship.

The perfection of the effect demonstrates the perfection of the cause, for a greater power brings about a more perfect effect. But God is the most perfect agent. Therefore, things created by Him obtain perfection from Him. So, to detract from the perfection of creatures is to detract from the perfection of divine power.

One who liberates his country by killing a tyrant is to be praised and rewarded.

Man reaches the highest point of his knowledge about God when he knows that he knows him not, inasmuch as he knows that that which is God transcends whatsoever he conceives of him.

It must be said that charity can, in no way, exist along with mortal sin.

Natural inclinations are present in things from God, who moves all things. So it is impossible for the natural inclinations of a species to be toward evil in itself. But there is in all perfect animals a natural inclination toward carnal union. Therefore it is impossible for carnal union to be evil in itself.

The greatness of the human being consists in this: that it is capable of the universe.

There is no order between created being and non-being, but there is between created and uncreated being.

The reason, however, why the philosopher may be likened to the poet is this: both are concerned with the marvellous.

The highest perfection of human life consists in the mind of man being detached from care, for the sake of God.

Down in adoration falling,Lo! the sacred Host we hail;Lo! o'er ancient forms departing,Newer rites of grace prevail;Faith for all defects supplying,Where the feeble senses fail.

Nothing is in the intellect that was not first in the senses.

The highest manifestation of life consists in this: that a being governs its own actions. A being that is always subject to the direction of another is somewhat of a dead thing. Variant translation: Now slavery has a certain likeness to death, hence it is also called civil death. For life is most evident in a thing's moving itself, while what can only be moved by another, seems to be as if dead. But it is manifest that a slave is not moved by himself, but only at his master's command.

A hymn is the praise of God with song; a song is the exultation of the mind dwelling on eternal things, bursting forth in the voice.

To become like God is the ultimate end of all.

O saving Victim, opening wideThe gate of heaven to man below,Our foes press on from every side,Thine aid supply, Thy strength bestow.

We can open our hearts to God, but only with Divine help.

If man of himself could in a perfect manner know all things visible and invisible, it would indeed be foolish to believe what he does not see. But our manner of knowing is so weak that no philosopher could perfectly investigate the nature of even one little fly.
