The Relevance of Philosophy: A Test

Before considering any philosophical issue or problem, ask yourself: Will the consideration of this issue, or the resolution of this problem, make any difference in how I live ( i.e. how I conduct myself, or interact with "the world" or others)? If it will not, pass on to other things; or at least recognize that the issue/problem is insignificant, and engage it as you would a kind of game or exercise.
