  In the case where we examine or study an object X qua Y or X in-the-respect-that X is Y, we study the consequences that follow from something's being an Y. In other words, Y determines the logical space of what we study. If X is a bronze triangle (a perceptible magnitude), to study X qua bronze will be to examine bronze and the properties that accrue to something that is bronze. To study X qua triangle is to study the properties that accrue to a triangle. Unless it follows from something's being a triangle that it must be bronze, the property of being bronze will not appear in one's examination.
