“Some things are worth dying for. Yes, really! And if we can’t get comfortable with admitting it and hearing others say it, then we’re going to have trouble caring enough—as well as coordinating enough—to put some effort into group projects. You’ve got to teach both sides of it, “That which can be destroyed by the truth should be,” and “That which the truth nourishes should thrive.”” (Eliezer Yudkowsky, Rationality)

Potentially usable phrases: That which can be destroyed by the truth should be and That which the truth nourishes should thrive.
