The reason is so simple, it is often ignored: IT FEELS GOOD! Well, until it doesnât â more on that later. Regardless of the Type of addiction (Substance, Process, Systemic or Codependency), certain chemicals get stimulated and released in the brain.

Haskell Curry defined mathematics simply as the science of formal systems. A formal system is a set of symbols, or tokens, and some rules telling how the tokens may be combined into formulas. In formal systems, the word axiom has a special meaning, different from the ordinary meaning of a self-evident truth.
With any definition, we must either postulate the existence of what has been defined (that is done in the case of a circle, Postulate 3), or we must prove it. By maintaining the logical separation of the definition of a thing and its existence, mathematics becomes a science in the same way physics is a science.
