I've been thinking about this dynamic alot. How I don't really trust my "feelings". I can feel a certain way but understand rationally I may have no real reason to feel that way. Like perceiving a slight were none was intended just because it felt that way or I think someone "should" act in XYZ manner.
Conversely I am wary of letting a feeling lead to engendering a thought that may or may not be true, but I feel that way so I act that way and make it true i.e. Othello when Iago played on his jealousy, or King Lear deciding his estate.
Yet if I think something I find valid, I can feel a way about the idea. If that makes any sense. I can be passionate about defending a good idea. I believe any notion that can't withstand scrutiny isn't worth holding.
