No doubt the fourth dimension, properly speaking, is not all something analogous to height, width, or depth, such as geometers understand these 3 dimensions. It is another thing much more complex, much more abstract, which would not be able to be defined in any manner in our present language. Let us suppose … that it is a different point of view, a manner of envisaging things in their eternal and immutable aspect, a manner of freezing oneself from movement in quantity in order to conceive only the single artistic quality of phenomena The vocabulary of our language is in fact conceived according to the given facts of three dimensional space. Words do not exist which are capable of defining exactly the strange, new sensations that are experienced when one raises himself forever above the vulgar world.
When one reaches the country of the fourth dimension when one is freed forever from the notions of space and time, it is with this intelligence that one thinks and reflects. Thanks to it, one finds himself blended with the entire universe, with so called future events, as with so called past events.
