Australian philosopher J.J.C. Smart even argues that "sometimes a person who is really an atheist may describe herself, even passionately, as an agnostic because of unreasonable generalized philosophical skepticism which would preclude us from saying that we know anything whatever, except perhaps the truths of mathematics and formal logic."
Škotski filozof J. J. C. Smart čak drži da "ponekad, osoba koja je zapravo ateist može opisati sebe, čak strastveno, kao agnostika zbog nerazumnog generalizirajućeg filozofskog skepticizma koji nas može spriječiti da tvrdimo kako znamo išta, osim možda matematiòkih istina i istina formalne logike."
