Does something come into existence because they are thinkable or are thought of?

There is a difference between the existence of thinker and the possible existence of the thinkable object.

In fact, for something to be thinkable there needs to be a thinker for the potential act of thinkability.

To think is to imply there is something to do the thinking. All actions are done by something.

This is true of qualities and relations as well. There need be something to embody the quality. And there need be things to relate to each other.

Without a thinker there are no thoughts and thinking.

The number of thoughts one has does not increase the number of objects in existence.
