“Existence. It can be doubted very much whether existence is a perfection or degree of reality; for it can be doubted whether existence is one of those things that can be conceived — that is, one of the parts of essence; or whether it is only a certain imaginary concept, such as that of heat and cold, which is a denomination only of our perception, not of the nature of things. Yet if we consider more accurately, [we shall see] that we conceive something more when we think that a thing A exists, than when we think that it is possible. Therefore it seems to be true that existence is a certain degree of reality; or certainly that it is some relation to degrees of reality. Existence is not a degree of reality, however; for of every degree of reality it is possible to understand the existence as well as the possibility. Existence will therefore be the superiority of the degrees of reality of one thing over the degrees of reality of an opposed thing. That is, that which is more perfect than all things mutually incompatibles exists, and conversely what exists is more perfect than the non-existent, but it is not true that existence itself is a perfection, since it is only a certain comparative relation [comparatio] of perfections among themselves.”—Leibniz in Determinist, Theist, Idealist by Robert Merrihew Adams.
