Bertrand Russell

"Yet Russell was more than a great intellect; he was also a political animal. From the beginning of his long professional life he emphasized the importance of practice as well as theory. He was twice imprisoned by the British government for his political utterances. With his razor-sharp irony and morally impassioned rhetoric, Russell took on the forces of injustice, ignorance, and cruelty; one of his chief weapons was the letter to the editor.".
