Mary Hesse quotes:

It could plausibly be argued that far from Christian theology having hampered the study of nature for fifteen hundred years, it was Greek corruptions of biblical Christianity which hampered it.

... one of the main functions of an analogy or model is to suggest extensions of the theory by considering extensions of the analogy, since more is known about the analogy than is known about the subject matter of the theory itself ... A collection of observable concepts in a purely formal hypothesis suggesting no analogy with anything would consequently not suggest either any directions for its own development.

Outside the practice of science itself, scientists have sometimes been the greatest offenders in adhering to dogmatic ideas against all the evidence.
