Thomas Aquinas Quotes

the intention of every man acting according to virtue is to follow the rule of reason, wherefore the intention of all the virtues is directed to the same end, so that all the virtues are connected together in the right reason of things to be done, viz. prudence,

Further, nothing, except sin, is contrary to an act of virtue. But war is contrary to peace. Therefore war is always a sin.

All things, by desiring their own perfection, desire God Himself.

Angels need an assumed body, not for themselves, but on our account.

"Human nature inclines us to have recourse to petition for the purpose of obtaining from another, especially from a person of higher rank, what we hope to receive from him. So prayer is recommended to men, that by it they may obtain from God what they hope to secure from Him. But the reason why prayer is necessary for obtaining something from a man is not the same as the reason for its necessity when there is question of obtaining a favor from God. Prayer is addressed to man, first, to lay bare the desire and the need of the petitioner, and secondly, to incline the mind of him to whom the prayer is addressed to grant the petition. These purposes have no place in the prayer that is sent up to God. When we pray we do not intend to manifest our needs or desires to God, for He knows all things. The Psalmist says to God: "Lord, all my desire is before Thee" and in the Gospel we are told: "Your Father knoweth that you have need of all these things." Again, the will of God is not influenced by human words to will what He had previously not willed. For, as we read in Numbers 23:19, "God is not a man, that He should lie, nor as the son of man, that He should be changed"; nor is God moved to repentance, as we are assured in 1 Kings 15:29. Prayer, then, for obtaining something from God, is necessary for man on account of the very one who prays, that he may reflect on his shortcomings and may turn his mind to desiring fervently and piously what he hopes to gain by his petition. In this way he is rendered fit to receive the favor."

Pipes are not to be used for teaching, nor any artificial instruments, as the harp, or the like: but whatsoever will make the hearers good men.

For it is essential to opinion that we assent to one of two opposite assertions with fear of the other, so that our adhesion is not firm: to science it is essential to have firm adhesion with intellectual vision, for science possesses certitude which results from the understanding of principles: while faith holds a middle place, for it surpasses opinion in so far as its adhesion is firm, but falls short of science in so far as it lacks vision.

Faith presupposes natural knowledge, even as grace presupposes nature, and perfection supposes something that can be perfected.

Tyrannical governance is unjust, since it is ordered to the private good of the ruler, not to the common good . . . And so disturbance of such governance does not have the character of rebellion . . . Rather, tyrants, who by seeking greater domination incite discontent and rebellion in the people subject to the them, are the rebels.

GREGORY OF NYSSA. How vain moreover is prayer for those who live by fate; Divine Providence is banished from the world together with piety, and man is made the mere instrument of the sidereal motions. For these they say move to action, not only the bodily members, but the thoughts of the mind. In a word, they who teach this, take away all that is in us, and the very nature of a contingency; which is nothing less than to overturn all things. For where will there be free will? but that which is in us must be free.

That which is asserted universally, by everyone, cannot possibly be totally false. For a false opinion is a kind of infirmity of the understanding, just as a false judgment concerning a proper sensible happens as the result of a weakness of the sense power involved. But defects, being outside the intention of nature, are accidental. And nothing accidental can be always and in all things; the judgment about savors given by every tasting cannot be false. Thus, the judgment uttered by everyone concerning truth cannot be erroneous.

Sciences are differentiated according to the various means through which knowledge is obtained. For the astronomer and the physicist both may prove the same conclusion: that the earth, for instance, is round: the astronomer by means of mathematics (i.e. abstracting from matter), but the physicist by means of matter itself. Hence there is no reason why those things which may be learned from philosophical science, so far as they can be known by natural reason, may not also be taught us by another science so far as they fall within revelation. Hence theology included in sacred doctrine differs in kind from that theology which is part of philosophy. SECOND ARTICLE [I, Q.

We should eliminate sin if we wish to eliminate the scourge of tyrants.

To love is to will the good of another.

Now in matters of action the reason directs all things in view of the end:
