Lewis Mumford

That nature does not care, one way or the other, is the true abyss. That only man cares, in his finitude facing nothing but death, alone with his contingency and the objective meaninglessness of his projecting meanings, is a truly unprecedented situation.

I remind everyone: Whether you school them at home or send them to school, you as a parent have the responsibility to make sure they learn and behave. Teachers and principals may help, but parents are the ones who must accept responsibility.
