The title of this paper may seem to involve a contradiction: my purpose is to show that it does not.
Individuals fall into two categories; those which depend for their existence upon the existence of other individuals, and those which do not. In the second category are found such things as shoes, ships, cabbages, kings, and discrete bits of sealing wax. These may be called individual substances, and the way in which the existence of a cabbage depends upon water and earth, or in which Descartes says the existence of all things depends upon God, will not be in point here. The individuals of the first category are characterized by a much more obvious kind of dependence. They include the sound of an individual shoe falling on the floor, the sinking of the Bismarck, the stupidity of George I, the centre of gravity of a bit of sealing wax. All these are individuals, though they are not individual substances. They are what I shall call abstract individuals, or abstract particulars.
