a tendency to stress the adverse aspects of a situation or event or to expect the worst possible outcome
Pessimism, when you get used to it, is just as agreeable as optimism — Arnold Bennett
in philosophy, the doctrine that this is the worst of all possible worlds
The modern scientific view appears to encourage pessimism. It eliminates human freedom, the bases of religious belief, and objective values: people become the puppets of their bodily states and upbringing. William James embraced religious belief and human freedom as satisfactory beliefs since they offered an escape from this pessimistic outcome — Professor Christopher Hookway
