There’s an interesting online psych project over here at Project Implicit…an interesting thing mentioned on Thought Capital’s blog post about the use of ’empirical data’ in ’evidenced-based meta-analyses’. I presume these EBMA’s are some sort of peculiar category of philosophical activity, perhaps connected to the idea of ’experimental philosophy’ which, whilst fascinating, seems to sometimes miss the point. Can evidence ever establish particular principles of thought? If not, then is it for a philosophy a question of giving up principles or of giving up evidence? Is there a dichotomy here that cannot (in principle or in fact) be resolved?
This difficulty, of what we might call the distinction between the quid facti and the quid juris is critical to any attempt to understand transcendental philosophy. There is an argument being made (James Williams, Dan Smith etc) that it is in fact principles that are crucial for Deleuze, that the quid juris has in some sense a priority derivable from an affinity of Deleuze’s method with that expressed by Leibniz ’Principle of Sufficient Reason’. Everything has to have a reason for existing, a ratio existendi, rather than simply a reason for being, ratio essendi. In fact, Smith argue, Leibniz in fact added other epistemological and metaphysical conditions in the PSR with the notions of ratio cognoscendi (a reason for how we can know the thing, the principle of indiscernibles) and a ratio fiendi (reason for becoming out of that which already is or law of continuity preventing arbitrary MacGuffin like inventions during the course of an account). The PSR aims to fulfill all that we would ask for in either of the quid moves, such that a question of fact or principle is capable of being responded to by understanding the sufficient reason for a thing.
