Quotes about Thomas Aquinas

Human law does not prescribe concerning all the acts of every virtue: but only in regard to those that are ordainable to the common good—either immediately, as when certain things are done directly for the common good—or mediately, as when a lawgiver prescribes certain things pertaining to good order, whereby the citizens are directed in the upholding of the common good of justice and peace.

To see this we must learn that some have said that relation is not a reality, but only an idea. But this is plainly seen to be false from the very fact that things themselves have a mutual natural order and habitude.

Secondly, a thing is said to preserve another 'per se' and directly, namely, when what is preserved depends on the preserver in such a way that it cannot exist without it. In this manner all creatures need to be preserved by God. For the being of every creature depends on God, so that not for a moment could it subsist, but would fall into nothingness were it not kept in being by the operation of the Divine power, as Gregory says (Moral. xvi).

Reply to Objection 4: Even if by a special privilege their predestination were revealed to some, it is not fitting that it should be revealed to everyone; because, if so, those who were not predestined would despair; and security would beget negligence in the predestined.

If forgers and malefactors are put to death by the secular power, there is much more reason for excommunicating and even putting to death one convicted of heresy.

The same Reply can be given to OBJ 2. For an essential term applied to the Father does not exclude the Son or the Holy Ghost, by reason of the unity of essence. Hence we must understand that in the text quoted the term "no one" [*Nemo = non-homo, i.e. no man] is not the same as "no man," which the word itself would seem to signify (for the person of the Father could not be excepted), but is taken according to the usual way of speaking in a distributive sense, to mean any rational nature.

Now the highest good existing in things is the good of the order of the universe, as the Philosopher clearly teaches in Metaph. xii.

Objection 1: It would seem that light is a body. For Augustine says (De Lib. Arb. iii, 5) that "light takes the first place among bodies."Therefore light is a body. Objection 2: Further, the Philosopher says (Topic. v, 2) that "light is a species of fire." But fire is a body, and therefore so is light.

Reply to Objection 3: It is not erroneous to say that men are transferred to the penalty of demons; but some erroneously stated that the demons are nothing but souls of the dead; and it is this that Chrysostom rejects.

Objection 1: It seems that God does not know evil things. For the Philosopher (De Anima iii) says that the intellect which is not in potentiality does not know privation. But "evil is the privation of good," as Augustine says (Confess. iii, 7). Therefore, as the intellect of God is never in potentiality, but is always in act, as is clear from the foregoing (A[2] ), it seems that God does not know evil things.

Reply to Objection 5: As was said above, the parts of the universe are ordered to each other, according as one acts on the other, and according as one is the end and exemplar of the other. But, as was said above, this can only happen to evil as joined to some good. Hence evil neither belongs to the perfection of the universe, nor does it come under the order of the same, except accidentally, that is, by reason of some good joined to it.

Reply to Objection 3: From effects not proportionate to the cause no perfect knowledge of that cause can be obtained. Yet from every effect the existence of the cause can be clearly demonstrated, and so we can demonstrate the existence of God from His effects; though from them we cannot perfectly know God as He is in His essence.
