Robert John Ackermann deals decisively with the problem of relativism that has plagued post-empiricist philosophy of science. Recognizing that theory and data are mediated by data domains (bordered data sets produced by scientific instruments), he argues that the use of instruments breaks the dependency of observation on theory and thus creates a reasoned basis for scientific objectivity. Originally published in 1985. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist (...) of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Studie over de filosofie van de in Oostenrijk geboren Engelse wijsgeer.

In this paper, I shall examine attempts to furnish formal models for deductive scientific explanation. All such attempts have had certain defects. The most serious of these defects is to be found in the fact that the extant models seem to be formally restrictive in ways that do not allow any obvious generalization of their conditions which will encompass the full range of all those scientific explanations which must be considered plausible candidates for translation into deductive models.

The fact that simplicity has been linked with induction by many philosophers of science, some of whom have proposed or supported criteria of “inductive simplicity,” means that the problem must be given some serious attention. I take “inductive simplicity” as a title, however, only by way of concession to these historical treatments, since it is precisely the burden of my paper to show that there is no such thing. So much for the conclusion. I shall spend the remainder of my (...) time arguing for it. (shrink)

Through close textual analysis, Ackermann (philosophy, U. of Massachusetts, Amherst) exposes the underlying unity and consistency in Nietzsche's thought. He challenges the common view that Nietzsche's work can best be understood as a collection of isolated insights and that each of several discrete periods of thought are based on a different set of values.

Franklin and Pickering agree that scientists in an experimental sequence, like the one to be discussed here, choose to accept certain experiments and their results as crucial, but disagree as to whether such choice can be justified in terms of an on-line estimate of evidential reliability. This paper suggests that it is possible to define a position between Franklin 's Bayesian objectivism and Pickering's social constructivism. This position depends on considering the sequence of improvement in material technique and instrumentation as (...) more important than any measure of reliability determined merely from such factors as evidential spread in relevant sequences, a factor that neither Franklin nor Pickering takes sufficiently into account.

This paper is intended to explore Jeffrey's proposal for the measurement of the simplicity of scientific laws. The first part is a sketch of Jeffreys' development of a view on simplicity, which will be followed by a discussion of what seem to be some rather crucial defects in the proposal as it stands. It will be suggested here that no plausible way of countering these defects seems available.

Many philosophers have written in the past as though it were nearly obvious to rational reflection that the existence of evil in this world is incompatible with the presumed properties of the Christian God, and they have assumed a proof of incompatibility to be easy to construct. An informal underpinning for this line of thought is easy to develop. Surely God in his benevolence finds evil to be evil, and hence has both the desire and the means, provided by his (...) omnipotence and omniscience, to eradicate it. But it remains a brute fact that evil exists. While this seems plausible enough at first glance, and seems damaging to the rationality of Christian belief, attempts to pin down a definite proof of incompatibility have encountered difficulties. The root difficulty is perhaps that the surface plausibility of incompatibility is ultimately mistaken. In what he calls a Free Will Defence against natural atheology, Alvin Plantinga has presented what seems a definitive proof, on rather modest assumptions, of the logical compatibility of God's nature and the existence of evil. Logic alone can neither prove nor disprove God's existence, since the defence rests on the empirical assumption that evil exists in this world. What Plantinga shows, put very simply, is that God may have created a world as good as any that an omnipotent, omniscient, and benevolent being might have created given that human beings must exist in that world. Whether Christianity ought to court logical rationality may seem highly dubious, but on the supposition that it does, Plantinga's proof that the existence of God is logically compatible with the existence of evil seems to me to settle the issue of whether Christianity is a possible object of rational belief, at least insofar as the problem of evil is considered the major obstacle to rationality of belief. Perhaps it is now clear that I do not intend here to attack the validity or the significance of Plantinga's proof. At the same time, I think it possible to argue for Plantinga's conclusion on other grounds, grounds that seem to me philosophically more appealing, and grounds that are manifestly compatible with the Biblical record. After briefly summarizing Plantinga's argument, I shall propose an alternative free will defence that circumvents some of the presuppositions of his arguments, an alternative that may be attractive to philosophers who are not interested in an ontology involving Plantinga's conception of possible worlds.

I regret to inform you that Allan Franklin is unable to be here because of the consequences of his collision with a truck in Boulder, Colorado several weeks ago. The three of us have decided to proceed with the symposium in his honor, even though it is now missing its fulcrum. The original point of the symposium was to have an informed discussion of two versions of atomic parity-violation experiments, versions that embody opposed philosophical conceptions of the experiments. The first (...) conception is embodied in Andy Pickering’s account in his Constructing Quarks, an account that is explicitly criticized by Allan Franklin’s more recent discussion in his Experiment, right or wrong (Pickering 1984; Franklin 1990). The symposium would have brought this confrontation into focus, with Franklin’s presentation of his critique followed by Pickering’s rejoinder at this symposium, both of them in sufficient command of the detailed history of the atomic parity-violation experiments to allow for the possibility of a useful exchange of differences of opinion.

Originally published in 1967. An introduction to the literature of nonstandard logic, in particular to those nonstandard logics known as many-valued logics. Part I expounds and discusses implicational calculi, modal logics and many-valued logics and their associated calculi. Part II considers the detailed development of various many-valued calculi, and some of the important metathereoms which have been proved for them. Applications of the calculi to problems in the philosophy are also surveyed. This work combines criticism with exposition to form a (...) comprehensive but concise survey of the field. (shrink)

In Howard Kahane's current reply to my previous discussion of Goodman's elimination rules, he suggests both that the notion of conflict required by the first elimination rule cannot be made clear, and that both proposed revisions of the second elimination rule are too strong [4]. These seem to me to be the points which require settlement, and I would like to discuss them in this paper.

This paper couples the variation and selection analogy utilized in evolutionary epistemology with the hermeneutical insight that novel data and theoretical texts are obscure in meaning. Dissensus must be valued as a distancing mechanism of variation on the space of possible meanings while argumentation attacks the initial obscurity. The objection that evolutionary accounts can only describe practice is countered by indicating how dissensus has normative purchase wherever science is producing novel text.

In order to explain the behavior of a human organism, it is necessary to take its environment into consideration. Except for very severe psychotic withdrawal, this has been recognized as a near triviality since Aristotle. But although consideration of the environment may be necessary, it is not sufficient, and it is now generally conceded that a man's behavior cannot be explained solely from a consideration of his present environment and a history of his responses to past environments.
