The link below will lead you to a remarkable interview with Noam Chomsky done by a young and, as you will see when the credits roll, extraordinarily well supported German journalist. Chomsky's perception of the current plight of humanity is historically accurate, and of great amplitude and thoroughness; no one alive today speaks with the same authority. A must see for anyone serious and sensitive enough to wonder about responsible action in this global mess we are all responsible for.
There is a problem, though, with Chomsky's otherwise accurate description of the general situation of humanity. He presents the current afflictions of the species as the result of the temporary rule of evil people and their incorrect thinking that must be overthrown by good people ready to act armed with the right ideas. In other words, he externalizes the problem from its source in self-centered thought itself, which is what traditional political and religious ideology has been doing forever, thus preserving the division, conflict, and suffering we have known all along. The situation that Chomsky describes is the net outcome of all the thought-based fluctuations of knowledge and influence that came before it.
What is necessary is not another gradual turn of the turnstile of knowledge and power in different places and at different social levels, but rather a veritable mutation of the mind that has forever been fragmented through its identification with different and contradictory ideas and desires. The possibility of this mutation is, of course, negated by the traditional mindset that can only serve separate tribal and egocentric identities battling each other over absurd worldly and otherworldly gain. Nothing will change significantly until our identification with predetermined ideologies and psychologies stops dividing and antagonizing us, and the species is thus able to recover from its millenary alienation from life.
