I would say that for Spinoza there is a continuous variation—and this is what it means to exist—of the force of existing or of the power of acting. How is this linked to my stupid example, which comes, however, from Spinoza, “Hello Pierre, hello Paul”? When I see Pierre who displeases me, an idea, the idea of Pierre, is given to me; when I see Paul who pleases me, the idea of Paul is given to me. Each one of these ideas in relation to me has a certain degree of reality or perfection. I would say that the idea of Paul, in relation to me, has more intrinsic perfection than the idea of Pierre since the idea of Paul contents me and the idea of Pierre upsets me. When the idea of Paul succeeds the idea of Pierre, it is agreeable to say that my force of existing or my power of acting is increased or improved; when, on the contrary, the situation is reversed, when after having seen someone who made me joyful I then see someone who makes me sad, I say that my power of acting is inhibited or obstructed.
