Capitalism now seems more likely a swamp, a bog, a quicksand in which humanity is presently flailing about, unable to extricate itself, perhaps doomed to perish within a few generations from the long term effects of the technology which seemed to Marx its greatest gift to humanity.

Kant says that we may regard ourselves as legislator of the moral law, and consider ourselves as its author, but not that we are legislators or authors of the law.

It is both theoretically mistaken and morally wrong to regard others as objects of investigation rather than partners in free rational communication.

Reason necessarily expresses itself through emotions and emotions are healthy only insofar as they are expressions of reason.

We usually can't know how, and we probably should not even ask, how our lives contribute to a better world.

Not only our moral life, but even our use of theoretical reason - on which we rely in rationally inquiring into nature - presupposes that we are free.

I think the term "Kantian constructivism" as an oxymoron. Kant was a constructivist about mathematics, but not about ethics.
