Injustice, poverty, slavery, ignorance -- these may be cured by reform or revolution. But men do not live only by fighting evils. They live by positive goals, individual and collective, a vast variety of them, seldom predictable, at times incompatible.

Sir Isaiah Berlin

Sir Isaiah Berlin, OM (6 June 1909 - 5 November 1997) was a philosopher and historian of ideas, regarded as one of the leading liberal thinkers of the twentieth century. He excelled as an essayist, lecturer and conversationalist; and as a brilliant speaker who delivered, rapidly and spontaneously, richly allusive and coherently structured material, whether for a lecture series at Oxford University or as a broadcaster on the BBC Third Programme, usually without a script. Many of his essays and lectures were later collected in book form
