Philosophy as Self-deception. But it's not clear to me what you mean by "self-deception." — Ciceronianus
I agree. This is the concept that does the heavy lifting.
Is philosophy done on the page or is it done in the person? The act of self-deception is a complicated task requiring knowing AND not knowing in the unity of consciousness, which seems to be a contradiction. In fact, I would say it cannot be done directly.
However, if it is possible to externalize the deception then it becomes possible. For example, one could play a prank on oneself by hiding an alarm clock set to go off 6 months later. In this case, it could be said you deceived yourself. In the same way, if philosophy is done on the page, then this externalized thing can be used for self-deception.
We write our thoughts (which are connected to a myriad of unwritten thoughts and possibles) onto the page, then we walk away. Eventually, we come back to these disconcerted words and they appear different to us because we started the process of forgetting. And at this point, self-deception can begin.
I neither know nor think I know
--Socrates
Is there a way out? If philosophy is a way of life, then one is always sitting with incompleteness (Experiential claim - Maybe the reader feels they know everything completely. In that case this does not apply.) In the face of this incompleteness, how can one claim to know anything in an absolute sense? The best one can muster is 'right at this second it looks good to me'.
