 According to Jung, there are four functions of consciousness or four ego functions. Two of them he called rational functions and two of them he called irrational or I would call them non-rational functions. So the two rational functions are thinking and feeling which is, from a Jungian point of view, those are the ways in which we establish values and make decisions. So feeling may be a more subjective orientation to valuing and decision making, but it is rational, absolutely as rational as what we think of as thinking. And the two non-rational functions are sensation and intuition. Sensation is just what you think it is, touch, sight, hearing, taste, and hands-on kinds of things of what needs to be done right now, and intuition is what we're going to talk about, but they are ways of getting information, they're just not cognitive. So here we are talking about our subjective decision making process, which from a Jungian point of view is feeling, and then this way of taking in information and what we do with it from an intuitive place.
