👉 Celtically is a term that refers to a system of thought or belief in which the concept of "c" (the root letter) is used as a symbol for "c" and "s". This system was first introduced by Scottish philosopher David Hume, who believed that it was possible to understand things through symbols. The idea behind this system is that the letters "c" and "s" can be seen as two different ways of expressing the same concept.
