Just because it is too late for modern societies to be maintained, does not mean it is too late for influencing the future. Just because it might be too late to significantly influence that future, does not mean it is too late to learn how to participate less in destructive or delusional behaviours.
A human being is a part of the whole, called by us Universe, a part limited in time and space. He experiences himself, his thoughts and feelings as something separated from the rest --- a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole nature in its beauty.
Albert Einstein
