Philosophy, as I understand the word, is a positive theoretical science, and a science in an early stage of development. As such it has no more to do with belief than any other science. Indeed, I am bound to confess that it is at present in so unsettled a condition, that if the ordinary theorems of molecular physics and of archaeology are but the ghosts of beliefs, then to my mind, the doctrines of the philosophers are little better than the ghosts of ghosts. I know this is an extremely heretical opinion.

I am half inclined to think we are all ghosts, Mr. Manders. It is not only what we have inherited from our fathers and mothers that exists again in us, but all sorts of old dead ideas and all kinds of old dead beliefs and things of that kind. They are not actually alive in us; but there they are dormant, all the same, and we can never be rid of them. Whenever I take up a newspaper and read it, I fancy I see ghosts creeping between the lines. There must be ghosts all over the world. They must be as countless as the grains of the sands, it seems to me. And we are so miserably afraid of the light, all of us.
Henrik Ibsen
You're from the isle of ghosts and, as you know, there are ghosts walking around all over the place over there. Loads of people have seen them, heard a voice or felt the cold temperature. I believe that they are between here and there, that they exist between the fourth and the fifth dimension and that they visit us frequently.
Dan Aykroyd
It seems to me that science has a much greater likelihood of being true in the main than any philosophy hitherto advanced (I do not, of course, except my own). In science there are many matters about which people are agreed; in philosophy there are none. Therefore, although each proposition in a science may be false, and it is practically certain that there are some that are false, yet we shall be wise to build our philosophy upon science, because the risk of error in philosophy is pretty sure to be greater than in science. If we could hope for certainty in philosophy, the matter would be otherwise, but so far as I can see such a hope would be chimerical.
Bertrand Russell
Science fiction is no more written for scientists than ghost stories are written for ghosts.
Brian Aldiss
Physics is the Science of Matter; Metaphysics the Science of Mind — the Science of Being, apart from accidents and properties — Ontology.
