“If it were right to overstep a little the limits of apodictic certainty befitting metaphysics, it would seem worth while to trace out some things pertaining not merely to the laws but even to the causes of sensuous intuition, which are only intellectually knowable. Of course the human mind is not affected by external things, and the world does not lie open to its insight infinitely, except as far as itself together with all other things is sustained by the same infinite power of one. Hence it does not perceive external things but by the presence of the same common sustaining cause; and hence space, which is the universal and necessary condition of the joint presence of everything known sensuously, may be called the phenomenal omnipresence, for the cause of the universe is not present to all things and everything, as being in their places, but their places, that is the relations of the substances, are possible, because it is intimately present to all. Furthermore, since the possibility of the changes and successions of all things whose principle as far as sensuously known resides in the concept of time, supposes the continuous existence of the subject whose opposite states succeed; that whose states are in flux, lasting not, however, unless sustained by another; the concept of time as one infinite and immutable in which all things are and last, is the phenomenal eternity of the general cause} But it seems more cautious to hug the shore of the cognitions granted to us by the mediocrity of our intellect than to be carried out upon the high seas of such mystic investigations, like Malebranche, whose opinion that we see all things in God is pretty nearly what has here been expounded.”

Card XXI : The World
The Symbolism of the Tarot (1913)
Context: The vision disappeared as suddenly as it appeared. A weird silence fell on me. "What does it mean?" I asked in wonder.
"It is the image of the world," the voice said, "but it can be understood only after the Temple has been entered. This is a vision of the world in the circle of Time, amidst the four principles. But thou seest differently because thou seest the world outside thyself. Learn to see it in thyself and thou wilt understand the infinite essence, hidden in all illusory forms. Understand that the world which thou knowest is only one of the aspects of the infinite world, and things and phenomena are merely hierolgyphics of deeper ideas."

Passages from the Life of a Philosopher (1864)
Context: There remains a third source from which we arrive at the knowledge of the existence of a supreme Creator, namely, from an examination of his works. Unlike transmitted testimony, which is weakened at every stage, this evidence derives confirmation from the progress of the individual as well as from the advancement of the knowledge of the race.
Almost all thinking men who have studied the laws which govern the animate and the inanimate world around us, agree that the belief in the existence of one Supreme Creator, possessed of infinite wisdom and power, is open to far less difficulties than the supposition of the absence of any cause, or of the existence of a plurality of causes.
