People are actually asking this question?

"Will enlightenment save the world?"

I find it very difficult to think that in this day and age people have to address these issues, though I'm kind of glad Warner did - though I did not read all the way through.

Though any reference to Eckart Tolle should tell you enough (though again I am supportive of the sentiments of the author of that last linked piece too.)

But...Eckart Tolle is not what Zen Buddhism is about.   As to the author of that piece writing this:

This was the case with Zen Buddhism in Japan during and before WWII, the cultivation of stillness, compassion and love can co-exist with the worst fascism and imperialism. The entire institution of Zen Buddhism – the masters, monks and professors supported the cruel and colonizing efforts of the state and emperor. They defended the “wars of compassion,” gorged themselves in killing and advocated merging the small self with the larger self of the state. This was all done within the monastical, academic and ethical systems of Zen Buddhism.

Some of it was.   Some of those folks lacked ethics and some did not.   This does not mean those who lacked a practice of ethics were not Zen Buddhists; but the ethics is a real thing with Zen Buddhism.

But let's put it this way: when one has understanding - which is one way in which awakening is put - one really can move about the world in a way to more effectively help people - or hurt them if one lacks an ethical practice.

If you're relying on Eckart Tolle for any kind of "wisdom" you already have difficulties.  Not only because of what Warner & Ms. Scofield say, but rather because things like what Tolle is saying have nothing to do with awakening, as far as I can tell.

I disagree with Warner though - meditation by itself won't save the world.   It can help, for sure, but it's in the day-to-day conscious life practice that world changing actually happens.
