In 1991 I devised a new course 'Science and the Paranormal', which was an introductory epistemology component for first-year philosophy at the University of New England. William Grey Scepticism is a pessimistic view of believing in nothing and doubting everything. Sceptics are often accused of being epistemic in view. They definitely take some things to the nth degree.
Nothing is accepted without evidence.
Reproduction under test conditions is critical to belief or acceptance in certain instances. Scepticism is creating a doubt on issues we feel have been proven as real or beyond doubt. The critical sceptic is a healthy sceptic, and it is probably advisable to be this way, but you would not want one for a friend. A sceptic will be largely disliked because they are untrusting and suspicious of even closest friends and relatives. Advantages of scepticism are few.
