SummaryEllis, Jardine and Putnam have argued that the would‐be scientific realist can only avoid being a metaphysical realist by becoming an “internal realist” . While metaphysical realism is unattractive, the approaches to truth offered by Ellis, Jardine and Putnam are quite unacceptable. However, the is no reason to think that one who wishes to be a scientific realist is limited to these two options.

The point of departure for all discussions of nonstatistical explanation in the philosophy of science has been the deductive‐nomological or covering law model of explanation that was given its most influential exposition by Carl Hempel, who was also the pioneering figure in the discussion of statistical explanation (see statistical explanation). On this account, to explain a particular event, we cite other particular events together with a general law or laws which "cover" what we want to explain. For example, we might (...) explain why a balloon expanded when placed on a radiator, by citing the fact that the radiator was hot together with the relevant laws relating heat to expansion.

We all think that science is special. Its products—its technological spin-off—dominate our lives which are thereby sometimes enriched and sometimes impoverished but always affected. Even the most outlandish critics of science such as Feyerabend implicitly recognize its success. Feyerabend told us that science was a congame. Scientists had so successfully hood-winked us into adopting its ideology that other equally legitimate forms of activity—alchemy, witchcraft and magic—lost out. He conjured up a vision of much enriched lives if only we could free (...) ourselves from the domination of the ‘one true ideology’ of science just as our ancestors freed us from the domination of the Church. But he told us these things in Switzerland and in California happily commuting between them in that most ubiquitous product of science—the aeroplane. (shrink)

David Hume is the greatest figure in the empiricist tradition in philosophy and was a particular source of inspiration for the logical positivists (see logical positivism). Hume was born in 1711 and entered Edinburgh University at the age of 12. After graduating, he had a varied career in commerce, diplomacy, as a librarian, and as a writer of history. Twice he was secretary to General St Clair and on one occasion set off with him on an expedition to drive the (...) French out of Canada. Forced back by the wind, it was decided instead to make a brief incursion on the coast of Brittany. This failed, for the expedition had maps of Canada, but none of Brittany. During a three‐year stay in France he wrote his major philosophical work Treatise of Human Nature. It appeared in 1739 and, in his own words, “fell dead‐born from the Press.” His Inquiry Concerning Human Understanding, which was intended to be a more popular version of book I of his Treatise, was published in 1748 but was only a little more favorably received. His six‐volume History of England, on the other hand, was a great success. He died in 1776, never having succeeded in his ambition to be appointed to a professorship of philosophy in Scotland, due to his religious skepticism. (shrink)

We think that science is special: its products ‐ technological spin‐offs ‐ dominate our lives. Sometimes it enriches our lives; sometimes it impoverishes them or even takes them away. For better or for worse, no institution has had more impact on the character of our existence this millennium than science. Penicillin, computers, atomic bombs make modern life modern life.
