Full Idea
To idealize is to trade accuracy in describing the actual for simplicity of description, and the compromise can sometimes be struck in different ways.

A Reaction
There is clearly rather more to idealisation than mere simplicity. A matchstick man is not an ideal man.

15868 | Idealisation idealises all of a thing's properties, but abstraction leaves some of them out [Harré] |
