The most interesting - in fact, inspiring - people I met there [Porto Alegre] are those who remain nameless: representatives of the international campesino movement, the East Timorese delegation,... - the usual heroes, who disappear, unknown, apart from the consequences of their work.

The reason I am a political radical is that I work on syntax. If I worked on semantics (which in fact I do), I'd be a good Thatcherite.

The main mineral in your cellphone, coltan [a black metallic ore], comes from the Eastern Congo. Multinational corporations are there exploiting the very rich mineral resources of the region.
