> Don’t Lose Your Idealism, Ground It.

This is almost universally true. We need morals/ideals, but they must be grounded in reality, in what is. If we just trudge along, we loose any vision for the future that could be better. If we just have idealism when we try to make things better, things usually get worse.

I'm not a constructivist (and definitely not a critical constructivist); I believe reality is knowable and consequential.

So have ideals; ground them in reality.
