Surely the world will be a better place, at least marginally, if people have a better understanding of Kant and Hegel, if Marx's thought its studied and appreciated, if people gain a better understanding of Fichte, whose philosophy is far more important than people realize.

Fichte is a necessary step to both Hegel and Marx.

Those who employ their modest talents as best they can do make a contribution to a better human future.

In my view, there was a long period in which analytical philosophy had little to say about ethics. I think their intellectual tools did not do well with it, and analytical philosophy was above all about revolutionizing the philosophical tool box. It was more or less assumed that the Truth about ethics was some form of utilitarianism (perhaps because some consequentialist calculus looked to them like a respectable tool). Kantian ethics was then interpreted as a particularly odious version of the False - "deontology" - and treated with contempt.

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

Kant can provide, and has provided, a good model for philosophers to think about the relation of metaphysics to science and scientific methodology.

Kant regards the universalizability test for maxims as focused on a very special sort of situation: one where the agent is tempted to make an exception to a recognized duty out of self-preference. The universalizability test is supposed help the agent to see, in a particular case of moral judgment, that self-preference is not a satisfactory reason for exempting yourself from a duty you recognize. Kant thinks, as a matter of human nature, that this situation arises often enough and that we need a canon of judgment to guard against it.
