For the acquisition of money is like generation rather than use: while the keeping of money, in so far as it is directed to facilitate the use of money, is like a habit.

Context

“On the contrary, The Philosopher says (Ethic. iv, 1) that "it belongs to a liberal man to surpass in giving." I answer that, It is proper to a liberal man to use money. Now the use of money consists in parting with it. For the acquisition of money is like generation rather than use: while the keeping of money, in so far as it is directed to facilitate the use of money, is like a habit. Now in parting with a thing—for instance, when we throw something—the farther we put it away the greater the force (virtus) employed. Hence parting with money by giving it to others proceeds from a greater virtue than when we spend it on ourselves.” source
