Tolerance is not, as is often thought, an attribute of urbanity that can be equated with other similar values, such as politeness. Nor is it - or at least it should not be - considered the oil that facilitates the smooth functioning of the engine of human desires, in spite of their differences of opinion. Rather, true tolerance takes root in the same soil as human rights. And this root is at the same time shared by liberty and truth. It is an untamed, barely diplomatic, root, burrowing deep in the soil of an absolute demand.
