[1] To understand metaphysical nihilism, one can look to the subtraction theory in its simplest form, proposed by Thomas Baldwin[citation needed].
Against the possible strength of this intuitive argument, some philosophers argue that there are necessarily some concrete objects.
E. J. Lowe has likewise argued that there are necessarily some concrete objects.
His argument runs as follows: Necessarily, there are some abstract objects, such as numbers.
The only possible abstract objects are sets or universals, but both of these depend on the existence of concrete objects (for sets, their members; for universals, the things that instantiate them).
