a good rule of thumb for detecting institutions, industries and belief systems which are deleterious to society and individuals is spotting those which try to suppress the truth (eg religion, capitalism, oil companies, the meat and dairy industry). that being the case, science and moral philosophy seem to be good bets for the future as they seek the truth, are not afraid of it and want to share it with the rest of the world. bad news for all you priests and politicians, capitalists and masters of war. your days are numbered, for the truth is out there and you cannot keep it from being heard forever.
so in conclusion let me just say that i nominate richard dawkins and peter singer as the spokespeople for a kinder, more enlightened future.
