It would be nice, wouldn't it? if we could get comfortable about the problem of freedom. Kant thinks that we can't.

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

Fichte is concerned with freedom as non-domination.

Consequentialist theories pretend that we can set some great big ends (the general happiness, human flourishing), provide ourselves with definite enough conceptions of them to make them the objects of instrumental reasoning, and then obtain enough reliable information about what actions will best promote them that we could regulate our conduct by these considerations alone.

What Smith and Marx have in common is that they were both philosophers of great vision and perceptiveness, deep humanity, and a sense of social reality that has been lost in the abstractly formalistic economic theories that have dominated the field since the last third of the nineteenth century.

Freedom is a permanent problem for us, both unavoidable and insoluble.

Many who are committed to reason and science have turned against religion altogether and treat it with fear and contempt.
