What is now "idea" for us How infinite the fall of this word, since

Note: "In England, Locke may be said to have been the first who
naturalized the term in its Cartesian universality. When, in common

him by Sidney, Spenser, Shakespeare, Hooker, etc., the meaning is
Platonic." Sir W. Hamilton. Abstract idea, Association of ideas, etc.
See under Abstract, Association, etc.
Syn.
– Notion; conception; thought; sentiment; fancy; image; perception;
impression; opinion; belief; observation; judgment; consideration;
view; design; intention; purpose; plan; model; pattern. There is
scarcely any other word which is subjected to such abusive treatment
as is the word idea, in the very general and indiscriminative way in
which it is employed, as it is used variously to signify almost any
act, state, or content of thought.
