“If the ethical - that is, social morality - is the highest and if there is in a person no residual incommensurability in some way such that this incommensurability is not evil then no categories are needed other than what Greek philosophy had... and what their wisdom amounts to is the beautiful proposition that basically everything is the same.”

“Ten thousand difficulties do not make one doubt, as I understand the subject; difficulty and doubt are incommensurate.”

“This is, of course, an easy Berlinian riposte. Start with some graceful hand waving about incommensurability; declare that nothing could reconcile these great goods; and (with a tip of trilby) commend liberal pluralism for living with the contradictions.”

“The propounders of what are called the "ethics of evolution," when the 'evolution of ethics' would usually better express the object of their speculations, adduce a number of more or less interesting facts and more or less sound arguments, in favour of the origin of the moral sentiments, in the same way as other natural phenomena, by a process of evolution. I have little doubt, for my own part, that they are on the right track; but as the immoral sentiments have no less been evolved, there is, so far, as much natural sanction for the one as the other. The thief and the murderer follow nature just as much as the philanthropist. Cosmic evolution may teach us how the good and the evil tendencies of man may have come about; but, in itself, it is incompetent to furnish any better reason why what we call good is preferable to what we call evil than we had before.”

“The delight we take in our senses is an implicit desire to know the ultimate reason for things, the highest cause. The desire for wisdom that philosophy etymologically is is a desire for the highest or divine causes. Philosophy culminates in theology. All other knowledge contains the seeds of contemplation of the divine.”

“People talk about beautiful relationships between two persons of the same sex. What is the best of that sort as compared with the friendship of man and wife where the best impulses and highest ideals of both are the same? There is no place for comparison between the two friendships; the one is earthly, the other divine.”
