In so many of his epistemological writings, Aristotle defends a sensible flavor of gradualism about our cognitive capacities: we start with the partial grasps afforded by what is better known to us, and if things go well, we end up with understandings of those objects better known by nature. The picture is of a step-wise process, rather than a transforming moment of illumination.

From what has been said, ‘tis easy to discover, what is so much enquired after, the principium Individuationis, and that ‘tis plain is Existence it self, which determines a Being of any sort to a particular time and place incommunicable to two Beings of the same kind.

While the Medievals spilled much ink over the Problem of Individuation, the Moderns scarcely mention it. My aim here is to explore what philosophical reasons, as opposed to historical or sociological ones, might lie behind the disappearance of a philosophical problem that vexed minds for centuries. I argue that Ockham clearly saw that a commitment to Nominalism removes the need to take seriously the Problem of Individuation. Suarez, who did take seriously the Problem, but who also advocated Nominalism, will be (...) shown to be subject to important Ockham-inspired arguments. To the extent, then, that Ockham's Nominalism carried the day into the Moderns, it is understandable, philosophically, that the Moderns should turn a deaf ear to the Problem of Individuation. (shrink)
