Equality does not mean that all plants must grow to the same height - a society of tall grass and dwarf trees, a jostle of conflicting jealousies. It means, in civic terms, an equal outlet for all talents; in political terms, that all votes will carry the same weight; and in religious terms that all beliefs will enjoy equal rights.
Despots play their part in the works of thinkers. Fettered words are terrible words. The writer doubles and trebles the power of his writing when a ruler imposes silence on the people. Something emerges from that enforced silence, a mysterious fullness which filters through and becomes steely in the thought.
