What does it means "a transcaction" and "an executed purpose?"
So far as you are wholly concentrated on bringing about a certain result, clearly the quicker and easier it is brought about the better. Your resolve to secure a sufficiency of food for yourself and your family will induce you to spend weary days in tilling the ground and tending livestock; but if Nature provided food and meat in abundance ready for the table, you would thank Nature for sparing you much labor and consider yourself so much the better off. An executed purpose, in short, is a transaction in which the time and energy spent on the execution are balanced against the resulting assets, and the ideal case is one in which the former approximates to zero and the latter to infinity. Purpose, then, justifies the efforts it exacts only conditionally, by their fruits.
