Optimism (OP-tuh-miz-um)
Origin
From French optimisme, formed from Latin optimus, meaning “best.” The term arose in European philosophical debate in the early 18th century and became particularly associated with the idea that the existing world was the best of all possible worlds.
Language Root
Latin optimus — “best,” the superlative of bonus (“good”).
Original Meaning
A philosophical doctrine holding that the world or universe is fundamentally ordered toward the best possible outcome or represents the best of possible worlds.
Evolution Over Time
The term became associated with the philosophy of Gottfried Wilhelm Leibniz, although optimism itself was coined and circulated by later writers discussing such ideas. Voltaire famously satirized philosophical optimism in his 1759 novel Candide. Over time, the word moved beyond philosophy and came to describe a general tendency to expect favorable outcomes or focus on positive possibilities. Modern psychology studies optimism as a pattern of expectations and explanatory style rather than simply “positive thinking.”
Modern Usage
A tendency to expect favorable outcomes, maintain hope about the future, or focus on positive possibilities even when difficulties exist.

Narrative
Optimism originally wasn’t just about looking on the bright side. It emerged from a much bigger philosophical question: could this actually be the best world possible? That debate moved from philosophy into everyday life, and optimism eventually became something deeply personal—the expectation that tomorrow can be better than today. Genuine optimism doesn’t require pretending that problems don’t exist. It means seeing the difficulty and still believing that a better outcome remains possible.
