Any purported conception of a non-mental object still deploys categories (substance, persistence, unity) that are, on Kantian grounds, contributions of the understanding rather than features of things-in-themselves.

Categories (in Kant's philosophy)(as the cognitive tools Kant thought were necessary for understanding): Basic mental structures or frameworks that Kant believed our brains use automatically to organize and make sense of all experiences—like organizing everything into concepts like cause-and-effect, space, and time.
Kant / Kantian(as the philosopher whose theory is being discussed): Immanuel Kant was an 18th-century German philosopher who argued that our minds actively shape how we experience the world, rather than passively receiving it. 'Kantian' means relating to his ideas.
conception(as used in epistemology (the study of knowledge)): An idea or mental image that your mind creates about something, which may or may not match reality perfectly.
non-mental object(in distinguishing between the mind and the external world): Something that exists outside your mind—like a chair, a tree, or a rock—as opposed to thoughts, feelings, or ideas that happen inside your head.

persistence(Weyl's distinction between two kinds of constancy)

Constancy maintained because a quantity is isolated and undisturbed, as opposed to actively adjusted

substance(Spinoza's metaphysics; criteria include (i) necessity and (ii) self-subsistence)

The fundamental existent that is wholly necessary and self-subsistent, not depending on anything else for its existence

things-in-themselves(Kantian metaphysics)

The intrinsic nature of objects as they exist independently of human perception and cognition, about which Kant claims we lack substantive knowledge

understanding (the faculty of)(the source of universality in this framework)

In Kant's philosophy, the mental power that takes raw sensory information and organizes it using concepts and rules to create knowledge.

unity(Derived from being by adding the notion of indivision alone.)

Being that is undivided; the concept of being with the purely negative addition of indivision.

This idea is waiting for its first supporting or challenging perspective.
