And I have another similar remark to make about these specimen drops of philosophy. Do not fancy I am libelling it, if I say it is like hemlock, aconite, or other deadly poison. Those too, though they have death in them, will not kill if a man scrapes off the tiniest particle with the edge of his nail and tastes it; if they are not taken in the right quantity, the right manner, and the right vehicle, the taker will not die; you were wrong in claiming that the least possible quantity is enough to base a generalization on.
