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.

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.

In general, those who defend capitalism are basically out of touch with reality.

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 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.

As Kant says, the contribution of any common laborer would be greater than that of the greatest philosopher unless the philosopher makes some contribution to establishing the rights of humanity.

Kant did think he had a moral route back to rational faith in God, for those who need it, and he thought that at some level, we all do need something like it.
