Per Dena’s thoughtful comments on my earlier post, and my follow-up, I am posting these excerpts from Thomas Aquinas’ Summa.  They come from the First Part of the Second Part (yeah, St. Thomas could have used an editor), where he talks about human passions.  In this particular question he discusses love, determing that (1) it belongs to the concupiscible power, (2) it is a passion, (3) it differs from dilection (which implies a choice, and an action of the will alone), and (4) it is properly divided into love of friendship and love of concupiscence.  I’ve just posted the respondeos here—the meat of the articles, where St. Thomas gives his own opinions.  You can read the full question, with the objections and Aquinas’ replies, here.  And that’s your dose of Scholasticism for the week!

 

1. Love is something pertaining to the appetite; since good is the object of both. Wherefore love differs according to the difference of appetites. For there is an appetite which arises from an apprehension existing, not in the subject of the appetite, but in some other: and this is called the “natural appetite.” Because natural things seek what is suitable to them according to their nature, by reason of an apprehension which is not in them, but in the Author of their nature, as stated in the I, 6, 1, ad 2; I, 103, 1, ad 1,3. And there is another appetite arising from an apprehension in the subject of the appetite, but from necessity and not from free-will. Such is, in irrational animals, the “sensitive appetite,” which, however, in man, has a certain share of liberty, in so far as it obeys reason. Again, there is another appetite following freely from an apprehension in the subject of the appetite. And this is the rational or intellectual appetite, which is called the “will.”

Now in each of these appetites, the name “love” is given to the principle movement towards the end loved. In the natural appetite the principle of this movement is the appetitive subject’s connaturalness with the thing to which it tends, and may be called “natural love”: thus the connaturalness of a heavy body for the centre, is by reason of its weight and may be called “natural love.” In like manner the aptitude of the sensitive appetite or of the will to some good, that is to say, its very complacency in good is called “sensitive love,” or “intellectual” or “rational love.” So that sensitive love is in the sensitive appetite, just as intellectual love is in the intellectual appetite. And it belongs to the concupiscible power, because it regards good absolutely, and not under the aspect of difficulty, which is the object of the irascible faculty.

2. Passion is the effect of the agent on the patient. Now a natural agent produces a twofold effect on the patient: for in the first place it gives it the form; and secondly it gives it the movement that results from the form. Thus the generator gives the generated body both weight and the movement resulting from weight: so that weight, from being the principle of movement to the place, which is connatural to that body by reason of its weight, can, in a way, be called “natural love.” In the same way the appetible object gives the appetite, first, a certain adaptation to itself, which consists in complacency in that object; and from this follows movement towards the appetible object. For “the appetitive movement is circular,” as stated in De Anima iii, 10; because the appetible object moves the appetite, introducing itself, as it were, into its intention; while the appetite moves towards the realization of the appetible object, so that the movement ends where it began. Accordingly, the first change wrought in the appetite by the appetible object is called “love,” and is nothing else than complacency in that object; and from this complacency results a movement towards that same object, and this movement is “desire”; and lastly, there is rest which is “joy.” Since, therefore, love consists in a change wrought in the appetite by the appetible object, it is evident that love is a passion: properly so called, according as it is in the concupiscible faculty; in a wider and extended sense, according as it is in the will.

3. We find four words referring in a way, to the same thing: viz. love, dilection, charity and friendship. They differ, however, in this, that “friendship,” according to the Philosopher (Ethic. viii, 5), “is like a habit,” whereas “love” and “dilection” are expressed by way of act or passion; and “charity” can be taken either way.

Moreover these three express act in different ways. For love has a wider signification than the others, since every dilection or charity is love, but not vice versa. Because dilection implies, in addition to love, a choice [electionem] made beforehand, as the very word denotes: and therefore dilection is not in the concupiscible power, but only in the will, and only in the rational nature. Charity denotes, in addition to love, a certain perfection of love, in so far as that which is loved is held to be of great price, as the word itself implies [Referring to the Latin “carus” (dear)].

4. As the Philosopher says (Rhet. ii, 4), “to love is to wish good to someone.” Hence the movement of love has a twofold tendency: towards the good which a man wishes to someone (to himself or to 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.

Now the members of this division are related as primary and secondary: since that which is loved with the love of friendship is loved simply and for itself; whereas that which is loved with the love of concupiscence, is loved, not simply and for itself, but for something else. For just as that which has existence, is a being simply, while that which exists in another is a relative being; so, because good is convertible with being, the good, which itself has goodness, is good simply; but that which is another’s good, is a relative good. Consequently the love with which a thing is loved, that it may have some good, is love simply; while the love, with which a thing is loved, that it may be another’s good, is relative love.
