At 19, I basically held the position that if you were intellectually honest and really wanted to get in touch with political reality then you had to smell tear-gas.
In ordinary life, the phenomenology of embodied emotions is an excellent example for dynamic changes between transparency and opacity: You can "directly perceive" that your wife is cheating you, or you can become aware of the possibility that maybe it is you who has a problem, that your "immediate" emotional representation of social reality might actually be a misrepresentation.
