347 [BERKELEY (George, B^). of Cloj/ne)] The Analyst ; or a Discourse addressed to an Infidel 

 Mathematician, wherein it is examined whether the Object, Principles, and Inferences of the 

 modern Analj'sis are more distinctly conceived or more evidently deduced than Religious Mysteries 

 and Points of Faith, by the Author of the Minute Philosopher, first edition, 2vith diagrams, 

 8vo. sewn (rare), 12* 6c? I734 



'In the Aiudy'st his theological philosophy wa:i further unfolded, in an argument meant to show that the higher 

 mathematics involve assumptions which as truly exclude definite or exliaustive conception as do any of the mysteries of 

 religion.' — I'rof. CampbeU Fmser. 



:U8 [ ] A Defence of Free-Thinking in Mathematics, in Answer to a Pamphlet of Phila- 



lethes Cantabrigiensis, intituled, ' Geometry no Friend to Infidelity'; also Appendix concerning 

 Mr. Walton's Vindication of the Principles of Fluxions, by the AUTHOR of the Minute 

 Philosopher, first edition, 8vo. sewn (rare), \0s 1785 



'In England the principles of fluxions were boldly attacke^l by Bp. Berkeley, who argued with great acutcness, 

 contending, among other things, that the fundamental idea of supposing a finite ratio to exist between terms absolutely 

 evanescent was absurd and unintelligible. The reply made by Jurin [f/. v. jmst] failed to remove all the objections. 

 Berkeley was the first to point out what was again shown later by Lazare Carnot, that correct answers were reached by 

 a compe)isation of errors.' — Prof. Ciijori.

'The most permanent result of his enthusiasjn was tlie work published in 1744, 'Siris' . . . The title 'Siris' was added 

 in the 2nd edition ; this appeared in 1744, others in 1746 and 1748 . . . The popularity was doubtless due to the medical 

 rather than to the metaphysical theories which were strongly blended together ; at the time it was the most popular of 

 Berkeley's writings.' — .Sir I^eslie Stephen.

 l)rolxibilities.

' His chief discoveries were the exponential calculus, the treatment of trigonometry as a branch of analysis, the con- 

 ditions for a geodesic, the determination of orthogonal trajectories, the solution of the brachistrochone, the statement that 

 a my of light traversed such a path that 2/[x(^s was a minimum, and the enunciation of the jirinciple of virtual work. I 

 heiieve that hf was the first to denote the accelerating effect of gravity by an algebraical sign g, and he thus arrived at the
