 Suspension is a core element of skepticism: the skeptic suspends judgment. However, if this means that the skeptic forms no beliefs whatsoever, then skepticism may be a kind of cognitive suicide. Arguably, belief-formation is a basic feature of human cognitive activity. It is not clear whether one can lead an ordinary human life without belief, or indeed, ancient opponents of the skeptics say, whether one can even survive. Perhaps even the simplest actions, such as eating or leaving a room without running into a wall, involve beliefs (Annas-Barnes 1985, 7; Burnyeat 1980). It is also hard to say whether someone who succeeded in not forming any beliefs could communicate with others, whether they could engage in philosophical investigation, or whether they could even think at all.
