Individuality thus is coexistent with Essence, it always 'concurs' with the Essence. It is contained in the (correctly taken) concept 'essence'. When St Thomas takes this Essence under the cutting-off of matter as designated (materia signata, [part of] the principle of individuation), then he gives up (in virtue of this cutting-off), not the individual, but the particular. At least, so it should be. When the materia signata is completely determined, that is, now involving precise sizes or dimensions, then he indeed gives up, when cutting this matter off, the particular.
