Logic and critical thinking skills are vital to successful and sensible living, but are lacking in modern education. If we can provide someone with the ability to think better, we then give that person the ability to successfully and constructively influence the world around them. Being able to reason gives anyone the ability to sift through the lies and misconceptions that make up so much of our lives.
