Kant attempted to work out a view of religion and religious belief according to which existing religions could be brought into harmony with modernity, science and reason.

In fact people do not know enough about themselves and what is good for them to form a sufficiently definite conception of the general happiness (or whatever the end is) to establish definite rules for its pursuit.

Kant thinks of judgment as a special faculty or talent of the mind, not reducible to discursive reasoning but cultivated through experience and practice.

Being aware of truths about what is good or right or about what we ought to do is not the same as deciding what to do. Nor can the former truths be derived from decisions about what to do, or about procedures for making such decisions, unless these procedures themselves rest in some way on the apprehension of truths about what we ought to do.

Fichte is concerned with freedom as non-domination.

Kant takes a free will to be a being or substance with the power to cause a state of the world (or a whole series of such states) spontaneously or from itself.

It is a culturally interesting (but also deeply depressing) fact that many religious claims seem to retain their emotional power for believers only if taken in ways that are intellectually unsupportable and even morally contemptible.
