Panglossian

The Panglossian view of natural selection is an appealing idea to us as human beings, you argue, because brains have foresight.

I know this sounds panglossian, and others have made strong arguments against such a scenario.

This is simply a Panglossian idea, policy as wishful thinking.

When my master adopted the Panglossian view of the universe I used no arguments that might cloud his serenity.
