- - Ayn Rand’s objectivism?
- (3) Ayn Rand’s objectivism?

Non-cognitivism contends that moral statements do not express propositions and have no truth values.
These theories include G. E. Moore’s intuitionism/agathistic consequentialism; Platonist ethics; divine command ethics, and Kantian ethics. Moral knowledge is a non-natural property known by (1) intuition, (2) god’s command or (3) a priori reasoning in these theories.
Ethical naturalism holds that moral knowledge is empirical in the sense that we can use the methods of the natural and social sciences to understand it. Moral concepts are reducible to, or definable in, non-ethical, natural terms. Most utilitarian theories are in the class of moral naturalism:
“even utilitarians who object to hedonism in its original, Benthamite form, as Mill expressly did, and utilitarians who stray even farther from the hedonistic fold, as I will suggest that Mill, perhaps unwittingly, also did, usually agree that the good is one or another kind of natural property. The dominant view, in other words, is that whatever is intrinsically good is part of nature. It is therefore fair to say that, with very few exceptions, utilitarians are ethical naturalists. One can be a utilitarian, though, and not be an ethical naturalist. For example, G. E. Moore, one of the founders modern analytic philosophy, was a utilitarian. He was as committed as Bentham or Mill to enhancing overall goodness by maximizing social utility, taking social utility to be the logical sum of individuals’ utilities. However, Moore famously opposed ethical naturalism, insisting that the very idea rest on what he disparagingly called the ‘naturalistic fallacy’. In direct opposition to Mill, Moore maintained that the good can only be a non natural property...” (Levine 2002: 136).According to Moore, all naturalist ethical theories commit the naturalistic fallacy.
The deontological theories (or duty/obligation based morality) hold that the basis of morality is duty and some acts are always right no matter what consequences they can cause (the best example of which is Kantian ethics or some forms of divine command theory; Kant famously said that it is always wrong to lie, no matter what the circumstances).
The Eudaemonist theories of ethics are those that hold that morality consists in some activity appropriate to man as a human being, and thus tend to emphasize the cultivation of virtue or excellence as the end of our action or moral life. These theories were mainly held by the ancient Greeks and Romans.
The utilitarian theories hold that utility/happiness is the end we should aim at, and the rightness or wrongness of an action is judged by ability to create more utility/happiness in the world.
Consequentialist theories hold that other ends are also important, and not just utility.

From a philosophical point of view I can only find moral nihilism right, as ethics do not have any ontological meaning.ReplyDelete
But from a positivist point of view, the scientific approach of evolutionary ethics (which can be linked to moral relativism) is more correct.
So morality does not exist as an objective reality, but actually is a creation of evolution as an adaptive strategy, but has a strong cultural influence (as culture is, also, an adaptive strategy).
It's an interesting matter.

Our moral instincts are a creation of evolution as an adaptive strategy.
But the question of whether there is a consistent and justifiable objective moral theory is a very different question.
(1) the mere evolutionary explanation of human moral instincts, with
(2) objective philosophical moral theories.
Ayn Rand's ethical system is a combination of virtue ethics, natural rights and consequentialism. But I would classify her into virtue ethics.ReplyDelete
I'm not confusing, indeed I pointed it here:ReplyDelete
"From a philosophical point of view I can only find moral nihilism right, as ethics do not have any ontological meaning."
I can't find any possible objective construction for ethics in a metaphysical way. So I'm a moral nihilist. But I'm a materialist, and from that point of view ethics is an absurd, as it's a metaphysical concept.
However I find that philosophical constructions for ethics come somewhat natural as a cause of that adaptive behaviour. It's just a more complex and mannered expression of it, due to a more developed culture.
