I recently came across a discussion essay in the International Journal of Philosophical Studies called "Hyperheaps" (15.1 [2007] pp. 121-123), in which the author, W. D. Hart, argues that "There is a least heap," by which he means there is an argument that can prove that there is a minimum number of elements that can compose the smallest possible heap of elements. His argument shows that the least heap is a heap of four spherical elements.
So let's put a stop to all this foolishness about philosophy being a waste of time.
