Nothing is demonstrable, unless the contrary implies a contradiction. Nothing, that is distinctly conceivable, implies a contradiction. Whatever we conceive as existent, we can also conceive as non-existent. There is no being, therefore, whose non-existence implies a contradiction. Consequently there is no being, whose existence is demonstrable.
The theory of science which permits and encourages the exclusion of so much that is true and real and existent cannot be considered a comprehensive science.
Actually, the true gourmet, like the true artist, is one of the unhappiest creatures existent. His trouble comes from so seldom finding what he constantly seeks: perfection.
Error is a supposition that pleasure and pain, that intelligence, substance, life, are existent in matter. Error is neither Mind nor one of Mind's faculties. Error is the contradiction of Truth. Error is a belief without understanding. Error is unreal because untrue. It is that which stemma to be and is not. If error were true, its truth would be error, and we should have a self-evident absurdity -namely, erroneous truth. Thus we should continue to lose the standard of Truth.
Geometry is knowledge of the eternally existent.
A species has to become pretty intellectually advanced in order to grasp the concept of death in the abstract, and to dream up the idea of immortality.

So, I am just saying that there are many existent proofs of species that have one, but not the other.
By believing passionately in that which doesn't exist, you create it and that which has not been sufficiently desired is what we call the non existent.
