- 145 Downloads
The notions of existence and necessity have held the interest of philosophers longer than many other problems in the philosophy of logic. The nature of necessity has been debated since the ancient Greeks; and many philosophers have pronounced their opinions in whether ‘existence is a predicate’. In this essay, I shall discuss the notion of existence. It serves to prepare the way for the later parts of this book, especially for ‘Existential Presuppositions and Uniqueness Presuppositions’, where similar methods are applied to the concepts of necessity and possibility.
