Author Quotes

The corruption of the best is the worst.

The movement of love has a twofold tendency: towards the good which a man wishes to someone, whether for himself or for another; and towards that to which he wishes some good. Accordingly, man has love of concupiscence towards the good that he wishes to another, and love of friendship towards him to whom he wishes good.

There cannot be a supreme evil, because... although evil always lessens good, yet it never wholly consumes it; and thus, since good always remains, nothing can be wholly and perfectly bad.

To know God exists in a general and confused way is implanted in us by nature, since God is man’s happiness. For man naturally desires happiness, and what is naturally desired by man must be naturally known to him. This, however, is not to know absolutely that God exists.

Youth is a cause of hope for three reasons... And these three reasons may be gathered from the three conditions of the good which is the object of hope - namely, that it is future, arduous and possible... For youth has much of the future before it, and little of the past; and therefore since memory is of the past, and hope of the future, it has little to remember and lives very much in hope. Again, youths, on account of the heat of their nature, are full of spirit, so that their heart expands, and it is owing to the heart being expanded that one tends to that which is arduous; therefore youths are spirited and hopeful. Likewise they who have not suffered defeat, nor had experience of obstacles to their efforts, are prone to count a thing possible to them. Therefore youths, through inexperience of obstacles and of their own shortcomings, easily count a thing possible, and consequently are of good hope.

Moral science is better occupied when treating of friendship than of justice.

Quarrels arise more frequently where there is no division of the things possessed.

The end of all my labors has come. All that I have written appears to me as much straw after the things that have been revealed to me.

The person who accepts the Church as an infallible guide will believe whatever the Church teaches.

There is a twofold retribution for the things that a man has done in life, one for his soul immediately upon its separation from the body, another at the resurrection of the body. The first retribution is to individuals severally, as individuals severally die: the second is to all men together, as all men shall rise together. Therefore there must be a twofold judgment: one of individuals, regarding the soul; another a general judgment, rendering to all men their due in soul and body… And further, since in the last judgment there will be question of the reward or punishment of persons present in visible bodily shape, it is fitting for that judgment to be a visible process.

To live well is to work well, to show a good activity.

Moral virtue can be without some of the intellectual virtues, namely, wisdom, science and art, but not without understanding and prudence. Moral virtue cannot be without prudence, because moral virtue is habit of choosing, that is, making us choose well.

Rarely affirm, seldom deny, always distinguish.

The end of every maker is himself.

The Philosopher [Aristotle] says in Metaphysics VI that good and evil, which are objects of the will, are in things, but truth and error, which are objects of the intellect, are in the mind.

There is but one Church in which men find salvation, just as outside the ark of Noah it was not possible for anyone to be saved.

To love God is something greater than to know Him.

Most men seem to live according to sense rather than reason.

Reason in man is rather like God in the world

The existence of a prime mover- nothing can move itself; there must be a first mover. The first mover is called God.

There is nothing on this earth more to be prized than true friendship.

To one who has faith, no explanation is necessary. To one without faith, no explanation is possible.

Music is the exaltation of the mind derived from things eternal, bursting forth in sound.

Reason may be employed in two ways to establish a point: first for the purpose of furnishing sufficient proof of some principle, as in natural science, where sufficient proof can be brought to show that the movement of the heavens is always of uniform velocity. Reason is employed in another way, not as furnishing a sufficient proof of a principle, but as confirming an already established principle, by showing the congruity of its results, as in astrology the theory of eccentrics and epicycles is considered as established because thereby the sensible appearances of the heavenly movements can be explained; not, however, as if this reason were sufficient, since some other theory might explain them.
