The story of the word

Plato's ἰδέα is built on the verb for seeing, so his eternal Forms are named for how a thing looks. The -ism was fastened onto Berkeley and then Kant in the 1790s to name the claim that what exists depends on mind. The everyday sense of impractical high-mindedness came later and has almost nothing to do with the doctrine; a philosophical idealist is describing the furniture of the universe, not their own good intentions.
