Since the Enlightenment, popular religion has rejected the Enlightenment path and transformed itself into a bastion of resistance against reason.

Those who see Smith as a defender of capitalism - as it existed in Marx's day, or as it exists today - show above all that they are not living in the real world. They are behaving as though the undeveloped form of capitalism Smith studied is still with us.

I don't think Kant's approach to religion is any longer viable in its original form. But that does not mean it is simply wrong or that we cannot learn from it.

We can never prove that we are free or integrate our freedom in any way into our objective conception of the causal order of nature.

Kant's treatments of rational theology and metaphysics were aimed primarily at theoretical questions. His attitude toward the pseudo-sciences of "special metaphysics" in Wolff and Baumgarten was always double-edged. He did see them as pseudo-sciences but also valued their doctrinal value and especially their regulative value for the empirical sciences. Like his views about religion, I don't think any of this is any longer viable in its original form.

Some empirical feelings, such as sympathy, are indispensable parts of certain moral virtues.

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