First, a PhD in philosophy. Subsequently? "Just" this: once gone through the University studies, somebody wishing to call himself (herself) a philosopher, must live his/her life philosophically (or, at least, try to). Which, for me, means: never stop searching for the meaning of life, never stop doubting and never refuse to put at stake his/her findings (meaning: let them undergo the test of facts and or the check of logic), never be scared either of changing them or change his/her behaviours and life style, as a consequence.
This search involves and concerns "small" things of everyday life as well as big questions, and it makes no big difference if it goes from the first to the second or vice-versa: small things and big questions always go together for a philosopher, as the two faces of a same coin.
So, in my opinion, this search is Philosophical Practice. A search for the meaning of life where
1. a philosopher uses different tools: critical thinking and sharp logic, but also meditation and contemplation.
2. a philosopher normally refers - besides other philosophers (western and eastern) - to as many traditional, academic, accredited authors as he/she is attuned with: scientists, historians, artists, even theologians.
3. a philosopher is willing to establish and renew human relationships and refuses isolation.
