This paper is about the meaning and function of identity statements involving proper names. There are two prominent views on this topic, according to which identity statements ascribe a relation: the object-view, on which identity statements ascribe a relation borne by all objects to themselves, and the name-view, on which an identity statement 'a is b' says that the names 'a' and 'b' codesignate. The object- and name-views may seem to exhaust the field. I make a case for treating identity (...) statements as sui generis instead of attempting to explain them by means of the idea that they ascribe a relation. My contention is that once we do this, no analysis is required. -/- I do not wish to insist that we stop saying that identity statements ascribe a relation. The point is that there is a fundamental disanalogy between identity statements and other two-termed statements which we overlook to our peril. This will be seen to parallel the more recognized disanalogy between existence statements and other one-termed statements. One way of registering the fundamental disanalogy is to say that identity statements are not relational, but this is not essential. Following my negative arguments in section 2, I employ some simple diagrammatical models in section 3 to exhibit the fundamental disanalogy. In a final section I respond to some possible objections which may be raised against this kind of approach. (shrink)

The central doctrine of Christianity is that God intervened in human history in the person of Jesus Christ in a unique way; and that quickly became understood as the doctrine that in Jesus Christ God became man. In AD 451 the Council of Chalcedon formulated that doctrine in a precise way utilizing the current philosophical terminology, which provided a standard for the orthodoxy of subsequent thought on this issue. It affirmed its belief in ‘our Lord Jesus Christ, … truly God (...) and truly man, … in two natures … the distinction of natures being in no way annulled by the union, but rather the characteristics of each nature being preserved and coming together to form one person’. One individual, one thing that is; and being a rational individual, one person. An individual's nature are those general properties which make it the sort of individual it is. The nature of my desk is to be a solid material object of a certain shape; the nature of the oak tree in the wood is to take in water and light, and to grow into a characteristic shape with characteristic leaves and give off oxygen. Chalcedon affirmed that the one individual Jesus Christ had a divine nature, was God that is; and it assumed that the divine nature was an essential nature. (shrink)

What is logical relevance? Anderson and Belnap say that the “modern classical tradition [,] stemming from Frege and Whitehead-Russell, gave no consideration whatsoever to the classical notion of relevance.” But just what is this classical notion? I argue that the relevance tradition is implicitly most deeply concerned with the containment of truth-grounds, less deeply with the containment of classes, and least of all with variable sharing in the Anderson–Belnap manner. Thus modern classical logicians such as Peirce, Frege, Russell, Wittgenstein, and (...) Quine are implicit relevantists on the deepest level. In showing this, I reunite two fields of logic which, strangely from the traditional point of view, have become basically separated from each other: relevance logic and diagram logic. I argue that there are two main concepts of relevance, intensional and extensional. The first is that of the relevantists, who overlook the presence of the second in modern classical logic. The second is the concept of truth-ground containment as following from in Wittgenstein’s Tractatus. I show that this second concept belongs to the diagram tradition of showing that the premisses contain the conclusion by the fact that the conclusion is diagrammed in the very act of diagramming the premisses. I argue that the extensional concept is primary, with at least five usable modern classical filters or constraints and indefinitely many secondary intensional filters or constraints. For the extensional concept is the genus of deductive relevance, and the filters define species. Also following the Tractatus, deductive relevance, or full truth-ground containment, is the limit of inductive relevance, or partial truth-ground containment. Purely extensional inductive or partial relevance has its filters or species too. Thus extensional relevance is more properly a universal concept of relevance or summum genus with modern classical deductive logic, relevantist deductive logic, and inductive logic as its three main domains.

Christian orthodoxy has maintained that in Jesus Christ God became man, i.e., acquired a human nature, while remaining God. Given two not unreasonable restrictions on the understanding of "man," that claim is perfectly coherent. But if the New Testament is correct in claiming that in some sense Christ was ignorant, weak, and temptable, we have to suppose that Christ had a divided mind; or, in traditional terminology, that the two natures did not totally interpenetrate.

Theological literacy is an important asset in the development of a comprehensive agricultural ethic and philosophy. Four areas are delimited in which theological reflection is relevant for agricultural study.
