Card 1.2 · Root I — Metaphysics
Cosmology (Philosophical)
Why is there something rather than nothing?
Philosophical cosmology asks why there is a universe at all, and why this one rather than some other. It is distinct from scientific cosmology, which asks how the universe developed given that it is here.
Where it sits
Under I. Metaphysics, beside 1.1 Ontology. Borders 1.8 Natural theology and 6.11 Philosophy of physics.
Narrower questions under this one:
- 1.2.1 Origins and First Cause Did anything ever start, or has it always been running?
- 1.2.2 Fine-Tuning and Necessity Could the universe have had different laws?
The rival answers
| Position | Claim |
|---|---|
| Theism | A necessary personal being explains contingent existence |
| Deism | A creator or first cause known by reason rather than special revelation; commonly conceived as not intervening miraculously after creation |
| Pantheism | The universe and the divine are identical |
| Brute-fact naturalism | Existence is simply unexplained, and no explanation is owed |
| Necessitarianism | The universe exists necessarily; nothing else was possible |
| Eternal cosmos | No temporal beginning — which removes the question of a beginning-cause, but not necessarily the question of why the cosmos exists or is sustained |
