What is philosophy? What’s the relationship between different philosophies? Is it better pursued solo, or in a group? Gilles Deleuze described philosophy as an activity involving the creation of new concepts (becoming 'friends with ideas', as he puts it), which differentiates it from science and art (science is about creating functions that map observed regularities and art is about creating percepts and affects.)
Considered the capstone of his collected work, this reading presents a good opportunity to reflect on how we make the truth our own, even as we jump from one thinker to another. Also discussed is the desirability of sharing a philosophical language with others, especially in light of the realization that our understanding is always, in a sense, personal and ever changing.
Does the philosopher in us benefit from trying to share a language with someone coming from a significantly different perspective? What should we expect from others when we ask "what do you mean"? What happens when our interest turns to polishing off ideas as testable propositions in the battlefield of ideas? It often seems as soon as we dislodge our concepts from what holds them together, we are left with only weak opinions. At what point do we become something more like scientific functionaries?
