To seem, to appear.

Form created in the mind, rather than the forms perceived through the five senses; an instance of thinking.

The operation by which such forms arise or are manipulated; the process of thinking; the agency by which thinking is accomplished.

"Without freedom of thought there can be no such thing as wisdom, and no such thing as public liberty without freedom of speech."

A way of thinking (associated with a group, nation or region).
