More particularly relevant to the subject before us is the teaching of Aquinas on liberality, which is a virtue directly connected with the user of property. Aquinas defines liberality as 'a virtue by which men use well all those exterior things which are given to us for sustenance.'[1] The limitations within which liberality should be practised are stated in the same article: 'As St. Basil and St. Ambrose say, God has given to many a superabundance of riches, in order that they might gain merit by their dispensing them well. Few things, however, suffice for one man; and therefore the liberal man will advantageously expend more on others than on himself. In the spiritual sphere a man must always care for himself before his neighbours; and also in temporal things liberality does not demand that a man should think of others to the exclusion of himself and those dependent on him.'[2]
[Footnote 1: II. ii. 117, 1.]
[Footnote 2: Ibid., ad. 1.]
'It is not necessary for liberality that one should give away so much of one's riches that not enough remains to sustain himself and to enable him to perform works of virtue. This complete giving away without reserve belongs to the state of the perfection of spiritual life, of which we shall treat lower down; but it must be known that to give one's goods liberally is an act of virtue which itself produces happiness.'[1] The author proceeds to discuss whether making use of money might be an act of liberality, and replies that 'as money is by its very nature to be classed among useful goods, because all exterior things are destined for the use of man, therefore the proper act of liberality is the good use of money and other riches.'[2] Moreover, 'it belongs to a virtuous man not simply to use well the goods which form the matter of his actions, but also to prepare the means and the occasions to use them well; thus the brave soldier sharpens his blade and keeps it in the scabbard, as well as exercising it on the enemy; in like manner, the liberal man should prepare and reserve his riches for a suitable use.'[3] It appears from this that to save part of one's annual income to provide against emergencies in the future, either by means of insurance or by investing in productive enterprises, is an act of liberality.
[Footnote 1: II. ii. 117, ad. 2.]
[Footnote 2: Ibid., ad. 3.]
[Footnote 3: Ibid., ad. 2. 'Potest concludi quod accipere et custodire modificata sunt acta liberalitatis…. Major per hoc probatur quod dantem multotiens et consumentem, nihil autem accipientem et custodientem cito derelinqueret substantia temporalis; et ita perirent omnis ejus actus quia non habent amplius quid dare et consumere…. Hic autem acceptio et custodia sic modificari debet. Primo quidem oportet ut non sit injusta; secundo quod non sit de cupiditate vel avaritia suspecta propter excessum; tertio quod non permittat labi substantiam propter defectum … Dare quando oportet et custodire quando oportet dare contrariantur; sed dare quando oportet et custodire quando oportet non contrariantur' (Buridan, Eth., iv. 2).]
The question is then discussed whether liberality is a part of justice. Aquinas concludes 'that liberality is not a species of justice, because justice renders to another what is his, but liberality gives him what is the giver's own. Still, it has a certain agreement with justice in two points; first that it is to another, as justice also is; secondly, that it is about exterior things like justice, though in another way. And therefore liberality is laid down by some to be a part of justice as a virtue annexed to justice as an accessory to a principal.'[1] Again, 'although liberality supposes not any legal debt as justice does, still it supposes a certain moral debt considering what is becoming in the person himself who practises the virtue, not as though he had any obligation to the other party; and therefore there is about it very little of the character of a debt.'[2]
