New Basis for Moral Philosophy [PDF ebook] 

Originally published in 1985, this book establishes that moral discourse is critical, rational and objective and challenges the ideology of value irrationalism behind contemporary liberalism. The book discusses the origins of the fact/value distinction, and calls into question the thesis that logical derivability or strict implication is the only legitimate relationship between propositions. A straightforward philosophical treatment of the subject, in the analytical tradition, it will be especially useful for undergraduate students.
