I think the work of great past philosophers is no longer in copyright. Is it possible to read them online somewhere?
More specifically I want these:
- Rene Descartes, Meditations on First Philosophy
- Friedrich Nietzsche, Beyond Good and Evil
- Aristotle, Metaphysics
- Aristotle, The Nicomachean Ethics
- Immanuel Kant, The Critique of Pure Reason
- Plato, The Republic
