"Do not let evil make you believe you can have secrets from it"

What does this mean? When I googled it, this came up. And this. I must read Kafka's Zürau Aphorisms. And I should probably eat better.

But also, listen to this.

To search for the unblemished truth all your life, and yet to recognise that such truth may not exist- that is who I want to be. Our greatest achievements are often acts of hopelessness, made with a conscious suspension of disbelief. I suppose that is why I love Orwell so much.

How do you serve dissent?

Do you serve it in a bowl, with a serving spoon? Or do you take that bowl, stand at the corner of a street, and pour it all over people?
