“Moreover, the simplest answer to such an ontological demonstration is the following: ‘All depends on whence you have your concept; if it is drawn from experience, well and good, for its object exists and needs no further proof; on the other hand, if it is hatched out of your own sinciput, then all its predicates are of no avail; it is just a phantom of your brain.” (Arthur Schopenhauer, On the Fourfold Root of The Principle of Sufficient Reason. Payne translation.)

Sinciput: the forehead.
