I finished Russian Philosophy by Copleston.
I sort of have 2 reasons for reading it.
My first reason is that I'm aiming to plow through Copleston's complete history of philosophy, of which this is one of the volumes, but one of the volumes which isn't included in the big monster-set I have of it. I think because it came later. Wikipedia lists the component volumes like this:
Volume 1: Greece and Rome
Volume 2: Augustine to Scotus
Volume 3: Ockham to Suarez
Volume 4: Descartes to Leibniz
Volume 5: Hobbes to Hume
Volume 6: Wolff to Kant
Volume 7: Fichte to Nietzsche
Volume 8: Bentham to Russell
Volume 9: Maine de Biran to Sartre
Volume 10: Russian Philosophy
Volume 11: Logical Positivism and Existentialism
In this scheme, I've only done 1 & 10.
That's two elevenths out of the way!
My second reason is that I'm planning to re-read Sciabarra's book, Ayn Rand: The Russian Radical. And I figured I should actually do a little homework so I had some context when Sciabarra starts talking about the philosophical traditions Rand would have been exposed to most in her formative years.
So that's why, having finished volume 1, I jumped ahead to 10. I have to admit, that I know enough of this stuff so that the Copleston material is mostly not really fresh to me. He's a good writer, so it's not actually boring, but it's a fairly fast read as philosophy goes. Thank goodness he writes so clearly!
Doesn't need to be a mystery.
