Distinction between Analytic and Synthetic Naturalism

In this paper, I will examine the distinction between analytic and synthetic naturalism. This division was first proposed by Kant in his attempt to find evidence for the fact that there seemed to be knowledge that was known independent from any particular experience (a priori), which was shared by all.(WEST) The goal is show that in the synthetic naturalism is plausible theory in meta-ethics, although it faces major criticism.

I- Analytic Naturalism

Analytic naturalism involves making the claim that moral properties, like morally wrong, are synonymous with natural properties. The use of a moral term, ‘S’, is regulated by the definition that the speaker attaches it to.(Jackson 1998) So, it seems that analytic naturalism is attached to sematic internalism. This means that a definition of a term is given solely in virtue of how things are in the mind a given speaker; anything from the outside environment does not contribute to the content of the terms the person says. (Rubin)

II- Synthetic Naturalism

Synthetic naturalism says that there is an a posteriori identity between moral and natural properties. For instance, there is an identity claim, which holds that water is identical with H2O. So, it is necessary for something that is water to also be the quantity of H2O.(RUBIN) This is considered to synthetic because the associations had between water and H2O can be completely different. The truth about water was found through empirical work, thus making it a posteriori.

Synthetic Naturalism proposes to adopt externalist semantics for moral and property terms. Externalist semantics allows for two terms to refer to the same property, even when the meanings are different. (PLATO STANFORD) So, it follows that the meanings of terms ...

IV-Conclusion

The analytic and synthetic distinction stands in the middle a great debate in philosophy due to the lack of clarity in both theories. The explanations and objections raised here have proven that analytic naturalism cannot be plausible because it applies proper names to natural terms. The analytic naturalist might respond by adjusting the theory and saying that moral terms do not have to equate natural terms, but that seems unlikely since that is the core of the argument. Thus, that leaves us with synthetic naturalism, which allows for the engagement in moral disagreement between speakers. Moral disagreement is fundamental if we are going to have moral philosophy.
