In order to account for the actual function of analogue models in extending theories to new domains, we argue that it is necessary to analyze the inference involved into a complex two dimensional form. This form must go horizontally from descriptions of entities used as a model to redescriptions of entities in the new domain, and it must go vertically from an observation language to a theoretical language having a different and exclusive logical syntax. This complex inference can only be (...) intelligible if we interpret theoretical terms in a platonic manner, a la Körner. (shrink)

That Kuhn is mistaken in drawing a sharp line between normal and revolutionary phases of science is shown by re-examining the role of models in extending theories to new phenomenal domains. In the light of this revision of the role of models, theory extension, which Kuhn includes in normal science, is shown to be continuous with theory replacement, which Kuhn includes in revolutionary science. Both involve language changes and the 'gestalt switches' associated with revolutionary science. These characteristics cannot be used (...) to demarcate the two phases as Kuhn seems to think.

Kant argues that any argument for a transcendent God presupposes the logically flawed ontological argument. The teleological argument cannot satisfy the demands of reason for a complete explanation of the meaning and purpose of our universe without support from the cosmological argument. I avoid the assumption of a perfect being, and hence the ontological argument, in my version of the cosmological argument. The necessary being can be identified with the creator of the universe by adding analogical mental relations. The creation (...) of the universe is then shown to reflect modern scientific cosmology as well as stories and metaphors in the Eastern and Western religious traditions and to resolve the problem of evil.

Kathryn Parsons attempts a criticism of the traditional approach to the problem of meaning invariance of predicate expressions when a theory is replaced by a successor. I have considered three types of cases which Parsons presents as counter-examples to Fine's criterion, and find that the first two do not succeed in refuting the criterion. The third, however, does suceed; and I argue that there is no way to revise Fine's criterion in order to remove the difficulty. Hence some non-traditional approach (...) to meaning invariance is required, or subjectivity in the science must be shown to be avoidable in spite of the incommensurability of theories. (shrink)

In spite of many claims by people who have had the kind of mystical experiences that I want to discuss, such experiences do not reveal any reality beyond the experience itself; nor does the experience itself constitute a cosmic principle such as the Godhead, Absolute, One or Chaos. These experiences are in the last analysis merely subjective experiences. I say ‘merely’ here only to deny that the experiences have any significance for the cosmologists; not to deny that the experience has (...) significant value for the experiencer. It may be that the experiences are the ultimate goal attainable by human beings. Their value does not depend on their being the ultimate truth. (shrink)
