Was Spinoza an Atheist? Steven Nadler on the Philosopher Who Defined Free Thought

"If there's a theme that unites all of Spinoza's philosophical writings, it's freedom: both personal freedom, how we become liberated from irrational passions, and political and social freedom, freedom of expression, freedom of belief and freedom of association." — Steven Nadler

Support Humanism Now & Join Our Community!⁠ Baruch Spinoza was excommunicated by his own community, condemned across Europe, and called the most dangerous philosopher of his age. Centuries later, scholars still argue over what he actually believed. In this episode, James Hodgson speaks with Steven Nadler, one of the world's foremost authorities on Spinoza, about the man, his radical ideas, and the case that Spinoza was, in the modern sense, a genuine atheist.

We explore what "atheist" even meant in the 17th century, why "God or nature" is not the same as pantheism, how Spinoza's defence of democracy and free expression anticipated modern liberal values, and why Einstein said his God was Spinoza's God.
