Fichte is a necessary step to both Hegel and Marx.

As I understand it, Kantian constructivism is partly a position in normative ethics and partly a position in metaethics. In metaethics, it is the position that ethical claims have truth values, but their truth conditions consist not in a set of objective facts to which they correspond, but instead in the outcome of some procedure of deliberation resulting in decisions about what to do.

Since we cannot know too much about the long term effects of our particular lives, and since success and fame are not good measures of the value of what we have done, it should be enough for any of us that as far as we can tell, in some small way we have made humanity's future better rather than worse.

I think the contribution people make is not proportionate to their fame or success. In fact, I think the relation is often inverse.

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

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.

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