... one might think that a certain degree of philosophical training would be very useful to a scientist. Scientists ought to be able to recognize how often philosophical issues arise in their work — that is, issues that cannot be resolved by arguments that make recourse solely to inference and empirical observation. In most cases, these issues arise because practicing scientists, like all people, are prone to philosophical errors. To take an obvious example, scientists can be prone to errors of elementary logic, and these can often go undetected by the peer review process and have a major impact on the literature — for instance, confusing correlation and causation, or confusing implication with a biconditional. Philosophy can provide a way of understanding and correcting such errors. It addresses a largely distinct set of questions that natural science alone cannot answer, but that must be answered for natural science to be properly conducted.-- Austin L. Hughes, The Folly of Scientism in The New Atlantis.
