In two previous posts I examined an early teacher of experimental philosophy, John Theophilus Desaguliers and a later one, George Adams. In this post I turn to a third teacher of experimental philosophy, Francis Hauksbee the Elder (1660–1713). (He was called ‘the Elder’ to differentiate him from his nephew of the same name who also taught experimental philosophy.) Hauksbee was one of the two most important first-generation pedagogues. (We will examine the other, John Keill, in my next post.)
He was a gifted instrument maker who not only developed a new much improved design of Robert Boyle’s air-pump, but also conducted a series of very important new experiments using this instrument. Many of these were published in the Philosophical Transactions. As a result of his proficiency with experimental apparatus he became a kind of de facto curator of experiments at the Royal Society in c. 1704 after Robert Hooke’s death. In addition he seconded James Hodgson FRS to carry out public lectures on experimental philosophy in London while he acted as the demonstrator.
By 1709 he himself was lecturing on experimental philosophy and continued this until his death in 1713. In 1709 he published a compilation volume of his air-pump experiments entitled Physico-Mechanical Experiments … touching Light and Electricity. This volume, in many ways, mimicked Boyle’s ground-breaking New Experiments Physico-mechanical touching the Spring of the Air (1660). (Even the titles are similar.) Hauksbee clearly saw himself as working in a tradition of experimental natural philosophy that extended back to Boyle.
The work gives us an interesting insight into how he viewed natural philosophy. He begins by telling us that:
The Learned World is now almost generally convinc’d, that instead of amusing themselves with Vain Hypotheses, which seem to differ little from Romances, there’s no other way of Improving Natural Philosophy, but by Demonstrations and Conclusions founded upon Experiments judiciously and accurately made. (Preface)
By now our readers should recognize the standard tropes of the experimental philosopher: the decrying of hypotheses; the likening of them to romances; the appeal to the necessity of experiment for the improving of natural philosophy.
Hauksbee goes on in the Preface to mention ‘The Honourable and most Excellent Mr. Boyle’ and ‘the … Incomparable Sir Isaac Newton’ implying that he himself is engaged in the same natural philosophical project. It is interesting to note, however, that there is no mention of the method of natural history as practised and promoted by Boyle in the Preface or in Hauksbee’s work. Hauksbee’s experimental practice was a natural extension of Boyle’s work, but at the same time methodologically discontinuous with it.
Hauksbee was also much quicker than Boyle to draw natural philosophical conclusions from his experiments. He did not, however, apply mathematics to his discoveries and he was later criticized by Desaguliers in his Course of Experimental Philosophy (1734) in so far as his experiments
were only shewn and explain’d as so many curious Phaenomena, and not made Use of as Mediums to prove a Series of philosophical Propositions in a mathematical Order, they laid no such Foundation for true Philosophy. (vol. 1, Preface)
Hauksbee may not have had developed views on the methodology of natural philosophy or much aptitude in mathematics, but he was a gifted experimenter and a keen promoter of experimental philosophy.
