You’re outlining four propositions associated with Donald Hoffman’s and Bernardo Kastrup’s debates about consciousness and physical reality, but the four statements are especially close to the assumptions Kastrup identifies in his discussion of analytic idealism and the standard physicalist worldview.

The key question is whether all four can be true simultaneously.

The four propositions

• First-person existence: Your conscious perceptions exist.
• Other minds: Other living entities have conscious experiences distinct from yours.
• Mind-independent reality: Something exists independently of, and outside, conscious perception.
• Causal generation: Things existing independently of conscious perception generate conscious perception.

How Kastrup would approach them

Kastrup would generally accept propositions 1 and 2. He would also accept a version of proposition 3, but he would challenge its interpretation: reality can exist independently of your individual consciousness without existing independently of consciousness as such.

He would reject proposition 4 as conventionally understood if it means that fundamentally nonconscious matter generates consciousness. In analytic idealism, consciousness is fundamental, and what we call the physical world is how the activities of consciousness appear from an external perspective.

Proposition	Kastrup’s position
1. Your conscious perceptions exist	Accept
2. Other minds exist	Accept
3. Reality exists independently of your perception	Accept, with qualification
4. Mind-independent things generate consciousness	Reject if this means nonconscious matter produces consciousness

The crucial distinction

The phrase “independently of conscious perception” can mean two different things:

• Independently of your personal perception: The world continues to exist when you are not looking at it.
• Independently of all consciousness: Reality exists in itself without consciousness being fundamental to it.

Kastrup accepts the first but rejects the second. He proposes that the world we perceive is the extrinsic appearance of a deeper, universal conscious reality.

So, if your question is whether propositions 1–4 are all true according to Kastrup, the answer is not as written. Proposition 4 is the principal point of disagreement, and proposition 3 depends on what “independently” means.

One question to clarify your argument: Are you proposing these four statements as assumptions that must be true for any coherent worldview, or are you asking whether Kastrup’s own philosophy entails all four?
