Skepticism is a very healthy mental outlook, frostythesnowman! If you don't agree, it will only cost you fifty dollars to come see the witch hiding in my attic or the invisible spray l have for your car that protects against tax audits. Expectthose with extraordinary claims to provide extraordinary evidence before you believe, and your view of reality will be the one most likely to mesh with actual reality.
Sceptic is the British (and hence traditional Australian spelling) of skeptic (or at least used to be) - and is pronounced the same way. Maybe you were thinking of septic.
