My opinion concerning God differs widely from that which is ordinarily defended by modern Christians. For I hold that God is of all things the cause immanent, as the phrase is, not transient. I say that all things are in God and move in God, thus agreeing with Paul, and, perhaps, with all the ancient philosophers, though the phraseology may be different ; I will even venture to affirm that I agree with all the ancient Hebrews, in so far as one may judge from their traditions, though these are in many ways corrupted. The supposition of some, that I endeavour to prove in the Tractatus Theologico-Politicus the unity of God and Nature (meaning by the latter a certain mass or corporeal matter), is wholly erroneous. As regards miracles, I am of opinion that the revelation of God can only be established by the wisdom of the doctrine, not by miracles, or in other words by ignorance.

I had hoped that out of so many stories you would at least have produced one or two, which could hardly be questioned, and which would clearly show that ghosts or spectres exist. The case you relate... seems to me laughable. In like manner it would be tedious here to examine all the stories of people, who have written on these trifles. To be brief, I cite the instance of Julius Caesar, who, as Suetonius testifies, laughed at such things and yet was happy. ...And so should all who reflect on the human imagination, and the effects of the emotions, laugh at such notions; whatever Lavater and others, who have gone dreaming with him in the matter, may produce to the contrary.

If I had as clear an idea of ghosts, as I have of a triangle or a circle, I should not in the least hesitate to affirm that they had been created by God; but as the idea I possess of them is just like the ideas, which my imagination forms of harpies, gryphons, hydras, &c., I cannot consider them as anything but dreams, which differ from God as totally as that which is not differs from that which is.

This I know, that between finite and infinite there is no comparison; so that the difference between God and the greatest and most excellent created thing is no less than the difference between God and the least created thing.
