What does optimism mean?
Optimism describes the habit of expecting that events will turn out well, or that problems can be overcome and improved. It is commonly used to characterize a person’s outlook, a community’s mood, or confidence in a future result. The term can be mildly approving, especially when it describes a constructive response to uncertainty, as in “cautious optimism.” It can also carry a warning implication when optimism is unrealistic or based on insufficient evidence. In philosophy, optimism has a more specific meaning: the view that the world and human nature are fundamentally good, or that the best outcome is ultimately attainable. In everyday use, optimism is usually an uncountable noun, and related forms such as optimist and optimistic are more common than its rare plural.
