Russell was wrong. Mathematics possesses neither truth nor beauty. Mathematics are a poor representation of truth at best and can never come close to providing an adequate proof for anything. Having been educated in mathematics from the age of 4 to the age of 26, I have not been impressed even a single time by a mathematician's "wisdom".
Let's be clear. It is not difficult to do mathematics. My dislike of mathematics does not stem from a lack of ability. Mathematics is actually easy as fuck. That doesn't make it accurate. It doesn't make it true. It doesn't mean that mathematics represent reality in any way, shape, or form.

Mathematics are mere intellectual masturbation. Mathematicians work with the presumption of the truth of their premises and never question the validity of such reasoning. Worse yet are the pure mathematicians who honestly do not care at all about reality and instead only care that such-and-such equation works because so-and-so invented a rule which makes it work. They do not care if the rule is accurate to reality. They do not care about reality at all. Only about whether abstract statement x is coherent given the truth of abstract statement y -- and philosophers have done a better job of determining that than mathematicians ever could.
