What is 'feeling'?

When people claim to feel this way or that way about something, they actually mean 'think', not feel.
Thinking is based upon memory, experience and opinion. It is not feeling.

Physical touch is not feeling. It is sensation.

Emotions are not feelings, they are responses to events. Emotions are related to thoughts. Emotion is commonly used as a form of blackmail.
What we think of as being an emotional 'feeling' is in fact an attempt to control events, to shape circumstances to suit our preferences.

So, what is feeling?
