With word and deed we insert ourselves into the human world, and this insertion is like a second birth, in which we confirm and take upon ourselves the naked fact of our original physical appearance. This insertion is not forced upon us by necessity, like labor, and it is not prompted by utility, like work. It may be stimulated by the presence of others whose company we may wish to join, but it is never conditioned by them; its impulse springs from the beginning which came into the world when we were born and to which we respond by beginning something new on our own initiative. To act, in its most general sense, means to take an initiative, to begin (as the Greek word archein, “to begin,” “to lead,” and eventually “to rule,” indicates), to set something into motion (which is the original meaning of the Latin agere). Because they are initium, newcomers and beginners by virtue of birth, men take initiative, are prompted into action. [Initium] ergout esset, creatus est homo, ante quern nullus fuit (“that there be a beginning, man was created before whom there was nobody”), said Augustine in his political philosophy. This beginning is not the same as the beginning of the world; it is not the beginning of something but of somebody, who is a beginner himself. With the creation of man, the principle of beginning came into the world itself, which, of course, is only another way of saying that the principle of freedom was created when man was created but not before.
