In Making It Explicit (1994) Robert Brandom claims that we may distinguish those linguistic expressions with object-representational purport — the singular terms — from others merely by the structure of their inferential relations. A good part of his inferentialist program rests on this claim. At first blush it can seem implausible: linguistic expressions stand in inferential relations to each other, so how could we appeal to those relations to decide on the obtaining of what seems to be relation between linguistic expressions and objects in general (viz., x purports to represent y)? It is perhaps not surprising then that Brandom's proposal fails. But it definitely is surprising how it fails. The problem is that in order to specify the sort of generality there is to an expression's inferential role, one must appeal to some version of the traditional distinction between extensional and nonextensional occurrences of expressions, and there appears to be no way to draw anything like that distinction in inferentialist terms. For the inferential proprieties governing the different occurrences an expression can have are so varied that they do not determine a binary partition of those occurrences.

Given that it seems uncontroversial that Socrates displays considerable contempt towards rhetoric in the Gorgias,the title of this paper might strike one as an oxymoron. Indeed, a reading of the text has more than once encouraged scholars to posit an Opposition between the elenctic procedures championed by Socrates and the rhetorical procedures of his interlocutors. At least three features have been highlighted that seem to indicate this contrast:

1. 1. the Socratic interest in short questions and answers versus his interlocutors’ use of long speeches (makrologia);

2. 2. the Socratic interest in truth regardless of the opinion of the many, the latter seeming an important concern of the rhetorician;

3. 3. the supposed Socratic appeal to the intellectual powers of the interlocutor, which is usually contrasted with the appeal to the emotions which is distinctive of rhetoric.

Locke is often thought to have introduced the topic of personal identity into philosophy when, in the second edition of the Essay, he distinguished the person from both the human being and the soul. Each of these entities differs from the others with respect to their identity conditions, and so they must be ontologically distinct. In particular, Locke claimed, a person cannot survive total memory loss, although a human being or a soul can.

In his book Practical Induction,Elijah Millgram mounts a powerful attack on instrumentalism. In particular, Millgram targets the instrumentalist claim that desires are by themselves reason-giving, that their reason-giving power is not grounded in any other independent fact. According to Millgram, desires, like beliefs, cannot license inferences (desires license inferences to conclusions about what we have reason to do; beliefs license inferences to other belief s and to conclusions about what we have reason to do) if they do not depend for their own justification on some prior mental states. Beliefs depend on prior beliefs and desires on feelings of pleasure and these in turn are grounded respectively in facts about the world and about desirability. If our desires would not depend in this way on other facts it would be possible for us to rationally desire what we want when we want; we could, as he puts it, ‘desire at will.'

It is relatively common for philosophers to doubt whether we have any reason to act as morality requires. But it is very difficult to find philosophers who are willing to doubt, in a similar way, the idea that we have reason to act as instrumental rationality requires; reason, that is, to take effective steps toward attaining the ends we have accepted as our own. The inference from the fact that a certain action is an effective means of satisfying an agent's ends to the conclusion that that agent has reason to perform that action is held by almost everyone to be, as it is sometimes said, automatic:once it is determined that the action in question bears the specified relation to one's goals, nothing more needs to be shown. But fewer philosophers are willing to grant that morality possesses this sort of automatic reason-giving force. Rather, it is quite commonly held that some additional consideration needs to be cited in order to show that an agent has reason to act as she is morally required. The fact that an action is morally required, claim those who adhere to this type of position, is not enough in itself.

In both popular and technical discussion we often find the pairs of opposed terms ‘innate/acquired,’ ‘due to genes/due to environment,’ ‘nature/nurture,’ and so forth. They appear to be used as if they all captured a genuine distinction, and the same distinction at that. A related family of opposed pairs is held to describe the difference between those who attribute a certain trait to ‘nature’ and those who attribute it to ‘nurture’: ‘nativists’ versus ‘constructivists’ is one such pair. Chomsky and his followers are often described as ‘nativists’ regarding certain features of language. On a cursory examination, many of the claims of Evolutionary Psychology bear the appearance of ‘nativism.’ That is, it looks as though Evolutionary Psychologists are making claims to the effect that many features of the mind which are often thought to be due to ‘nurture’ are in fact due to ‘nature.’ However, two of the genre's leading practitioners, John Tooby and Leda Cosmides, vigorously deny that this is their position.

This paper explores the conceptual dimension in theory acceptance, throws light on the notion of coherence between theories, and emphasizes the role of coherence between theories in theory acceptance. It is important, however, to recognize that the empirical-conceptual distinction, like most other distinctions in philosophy, is only pragmatic because purely empirical or conceptual notions in science are rare. That is, the term ‘conceptual’ is actually used in the sense of ‘mostly conceptual’, and the term ‘empirical’ signifies what is predominantly empirical. Yet it is useful in many contexts to speak of conceptual and empirical merits of theories separately. Among the commonly discussed conceptual merits of a theory are internal consistency, simplicity, comprehensiveness, and coherence with existing theories. Empirical merits include accommodating known evidence and passing experimental tests. The focus of this paper is coherence between theories.
