Sometimes the question ‘Who invented X?’ has no determinate answer, in spite of claims of particular individuals. One thinks of questions like ‘Who invented the internet?’ and the various dubious claims to this honour. Christoph Lüthy has argued quite convincingly that ‘the microscope was never invented’ (Early Science and Medicine, 1, 1996, p. 2). I suggest that the same probably goes for the experimental philosophy: there is no single person or group of people who created it, rather it somehow ‘emerged’ in Europe sometime between the death of Francis Bacon in 1626 and the founding of the Royal Society in 1660. One place to look for answers is to trace the early uses of the term ‘experimental philosophy’.
Here is the evidence that I am aware of for the emergence of the term ‘experimental philosophy’ in early modern England. The first English work to use the term ‘experimental philosophy’ according to EEBO was Robert Boyle’s Spring of the Air in 1660. Interestingly, the term philosophia experimentalis had already appeared in the title of Nicola Cabeo’s Latin commentary on Aristotle’s Meteorology of 1646 and Boyle cites Cabeo’s book twice in Spring of the Air. The first English book to use the term in its title was Abraham Cowley’s A Proposition for the Advancement of Experimental Philosophy of 1661. From then on, however, books about experimental philosophy start to roll off the presses of England. Boyle’s Usefulness of Experimental Natural Philosophy and Henry Power’s Experimental Philosophy, both published in 1663, got the ball rolling. (Incidentally, Cabeo’s book was reprinted in Rome in 1686 under the title Philosophia experimentalis.) As for manuscript sources, the earliest use of the term ‘experimental philosophy’ that I have found is in Samuel Hartlib’s Ephemerides in 1635.
Another place to look for evidence for the inventor of the experimental philosophy is in discussions of natural philosophy and of experiment. It appears that Francis Bacon never used the term ‘experimental philosophy’, but he did develop a conception of experientia literata (learned experience), which might be thought to be a precursor of the experimental philosophy. This appears in Book 5 of his De augmentis scientiarum of 1623, where it is distinguished from interpretatio naturae (interpretation of nature). The experientia literata is a method of discovery proceeding from one experiment to another, whereas interpretatio naturae involves the transition from experiments to theory. But this doesn’t resemble the distinction between experimental and speculative philosophy very closely. For example, the experimental philosophy was, on the whole, opposed to speculation and hypotheses and there is no sense of opposition or tension in Bacon’s distinction.
Furthermore, a distinction between operative (or practical) and speculative philosophy was commonplace in scholastic divisions of knowledge in the late 16th and early 17th centuries, and this, no doubt provided the basic dichotomy on which the experimental/speculative distinction was based. But the operative/speculative distinction doesn’t map very well onto the experimental/speculative distinction, not least because by ‘operative sciences’ the scholastics meant ethics, politics and oeconomy (that is, management of society) and not observation and experiment.
Who invented the experimental philosophy? I don’t think that there is a determinate answer to this question, but I’m happy to be corrected and am keen for suggestions as to where to look for more evidence.
