The fundamental sense of freedom is freedom from chains, from imprisonment, from enslavement by others. The rest is extension of this sense, or else metaphor.
Isaiah BerlinScience cannot destroy the consciousness of freedom, without which there is no morality and no art, but it can refute it.
Isaiah BerlinConformities are called for much more eagerly today than yesterday... skeptics, liberals, individuals with a taste for private life and their own inner standards of behavior, are objects of fear and derision and targets of persecution for either side... in the great ideological wars of our time.
Isaiah BerlinIf, as I believe, the ends of men are many, and not all of them are in principle compatible with each other, then the possibility of conflict - and of tragedy - can never wholly be eliminated from human life, either personal or social. The necessity of choosing between absolute claims is then an inescapable characteristic of the human condition. This gives its value to freedom as Acton conceived of it - as an end in itself, and not as a temporary need, arising out of our confused notions and irrational and disordered lives, a predicament which a panacea could one day put right.
