Siger de Brabant was a "Latin Averroist", who were famously criticized by such thinkers as Thomas Aquinas and Bonaventure for rationalist tendencies.

Individuation is an important philosophical concept with a wide range of uses, and basically refers to how universals (such as "dog" and "man") are instantiated in individuals (such as "Fido" and "Socrates"). Jorge E. Gracia wrote a monumental study on the issue: Individuation in Scholasticism. The Later Middle Ages and the Counter-Reformation 1150-1650

The best translation of "individuare" is "to individuate": it is a transitive verb whose subject is what makes a universal form actually individual. According to Aristotelian hylomorphism, "matter" is the usual candidate for the so-called "principium individuationis," i.e. "principle of individuation." Here is my full translation in light of that:

Since matter is not sufficient in itself to individuate, it is said that certain conditions of the matter and accidents of the individual, such as "being here" and "being now," individuate, from which universal reason abstracts.

The only part that I am hesitant about is the end: I would have expected "abstrahitur," since "ratio universalis" usually refers to a "universal account," i.e. "dog-ness." An account is abstracted, according to Scholastic terminology, and does not do the abstracting, which is the work of reason. By suspicion, which I don't have the time to confirm, is that this is a relic of Siger's Averroism: Averroes famously taught that the so-called "agent intellect," which abstracts universal concepts, is not particular to individuals, but that it is common to all men. He might plausibly refer to it as "universalis ratio," i.e. the reason shared by all people.
