Normativity concerns what we ought to think or do and the evaluations we make. For example, we say that we ought to think consistently, we ought to keep our promises, or that Mozart is a better composer than Salieri. Yet what philosophical moral can we draw from the apparent absence of normativity in the scientific image of the world? For scientific naturalists, the moral is that the normative must be reduced to the nonnormative, while for nonnaturalists, the moral is that there must be a transcendent realm of norms. _Naturalism and Normativity_ engages with both sides of this debate. Essays explore philosophical options for understanding normativity in the space between scientific naturalism and Platonic supernaturalism. They articulate a liberal conception of philosophy that is neither reducible to the sciences nor completely independent of them—yet one that maintains the right to call itself naturalism. Contributors think in new ways about the relations among the scientific worldview, our experience of norms and values, and our movements in the space of reason. Detailed discussions include the relationship between philosophy and science, physicalism and ontological pluralism, the realm of the ordinary, objectivity and subjectivity, truth and justification, and the liberal naturalisms of Donald Davidson, John Dewey, John McDowell, and Ludwig Wittgenstein.

According to some philosophers, philosophical realism is an obsolete, specious and irrelevant conceptio. In this essay I argue that this thesis is deeply flawed because the issue of realism is philosophically inescapable. Then I discuss two versions of philosophical realism that are particularly widespread today: common sense realism and scientific realism. These conceptions tend to be hegemonic, and consequently often in conflict with each other. The biggest challenge for philosophical realism over the next few years will be to try and harmonize them.

In this paper, we first set out three requirements that each e-theory – a theory whose task is to explain data – must fulfill in order to be one such good theory: i) an ontological requirement, i.e. adequate simplicity, ii) a methodological requirement, i.e. plurality of research procedures, iii) an epistemological requirement, i.e. compatibility with the best available epistemical procedures. Moreover, we will claim that from the metaphilosophical point of view, unlike scientific naturalism on the one hand and supernaturalism on the other, liberal naturalism is the only philosophical approach capable of fulfilling all such requirements.
