**Eliphas Levi, 1861**

## Each letter is an universal and an absolute conception, governed only by the number represented by the letter. The science of signs begins with the science of letters.

## Letters are absolute ideas. Absolute ideas are numbers. Numbers are perfect signs.

## In using ideas with numbers, one can operate upon the ideas like one can operate upon number and arrive at the mathematics of truth.
