Is there a theory (Perhaps Freudian) concerning that of "Being" and that of "Happening"? I vaguely recall learning about it many years ago in H.S. Psych, but of course any search for either of these keywords results in non-relevant returns as both being and happening are common words.
The question is, if there is a theory concerning these concepts - what is the gist? But as importantly, what are keywords that I could use to find useful results?
