The Analyst
Berkeley's 1734 'The Analyst, or a Discourse Addressed to an Infidel Mathematician' — critique of Newton's calculus and free-thinking mathematicians
Tradition: Anglo-Irish idealism / philosophy of mathematics / Anglican polemic
Berkeley's 1734 'The Analyst' — 'ghosts of departed quantities' — the philosophical critique of Newton's infinitesimal calculus
Published in 1734, 'The Analyst, or a Discourse Addressed to an Infidel Mathematician' is Berkeley's philosophical-mathematical critique of Newton's calculus of fluxions and Leibniz's differential calculus, addressed to Edmond Halley ('the Infidel Mathematician' — Berkeley believed that Halley's mathematics-confident-atheism had influenced the young Joseph Addison's deathbed disbelief). Berkeley argues that the foundations of the calculus — Newton's 'fluxions' (instantaneous rates of change), Leibniz's 'differentials' (infinitesimally small differences), and the use of 'evanescent increments' that vanish at the moment of being divided — are no more rigorous than the religious mysteries free-thinking mathematicians ridicule. Berkeley's most-quoted passage: 'What are these fluxions? The velocities of evanescent increments? And what are these same evanescent increments? They are neither finite quantities, nor quantities infinitely small, nor yet nothing. May we not call them the ghosts of departed quantities?' (§35). The argument is rhetorically devastating and philosophically substantial: the standard practice of the calculus in 1734 did rely on systematically setting infinitesimals first equal to a non-zero quantity (for purposes of cancelling) and then equal to zero (for purposes of arriving at a finite answer). Berkeley exposed real foundational difficulties that would not be properly resolved until the nineteenth-century arithmetisation of analysis by Cauchy, Weierstrass, and Dedekind. The book is credited with motivating that arithmetisation programme by the rigour-demand it placed on subsequent mathematical foundations.

School Embodiments
Defining eighteenth-century philosophy-of-mathematics polemic.
"What are these fluxions? The velocities of evanescent increments? And what are these same evanescent increments? They are neither finite quantities, nor quantities infinitely small, nor yet nothing. May we not call them the ghosts of departed quantities?" (The Analyst, §35)
Berkeleian-idealist anti-abstractionist framework.
"The same abstractionist confusion plagues mathematics and metaphysics." (The Analyst, §6)
Rationalist-critical methodology.
"The foundations of mathematics must withstand reason's examination." (The Analyst, preface)
Anti-free-thinking apologetic framework.
"Free-thinking mathematicians have no warrant for their religious scepticism." (The Analyst, opening)
Realism — but here against pretended-rigorous mathematical objects.
"Mathematical entities must be intelligible or be rejected." (The Analyst, §38)
Philosophy of science applied to Newton's mathematical methodology.
"The methods of the calculus are no better grounded than religious mystery." (The Analyst, §50)
Internal Tensions
Exposed real foundational difficulties in the calculus — credited with motivating the nineteenth-century arithmetisation of analysis. Berkeley's argument was philosophically substantial as well as rhetorically devastating; subsequent mathematicians (Lagrange, Cauchy, Weierstrass) had to work out the rigorous foundations the calculus had originally lacked.
I. Time
1734. Berkeley was 49 and had just returned to England from his three-year residence in Rhode Island (1729-31); he became Bishop of Cloyne later in 1734.
Attributes
II. Space
London publication; Berkeley's Anglo-Irish bishop-philosopher context. The Royal Society debate over the foundations of the calculus (Newtonian fluxions vs. Leibnizian differentials) was at its height in 1734.
Attributes
III. Matter
Single critical-philosophical pamphlet (~80 pages). Form is treatise-essayistic with numbered paragraphs (§§1-67) running through the argument.
Attributes
IV. Observer
Late Berkeley. The observer-philosopher is the Anglo-Irish bishop-philosopher (Berkeley would die in 1753) at the height of his anti-free-thinking apologetic work.
Attributes
V. Energy
Polemical-philosophical-mathematical energies. The pamphlet's rhetorical force was substantial — it was widely read and replied to (Jurin's 'Geometry No Friend to Infidelity', 1734; Robins's 'Discourse Concerning the Nature and Certainty of Sir Isaac Newton's Methods of Fluxions', 1735) and stimulated a substantial mathematical-foundational literature.
Attributes
VI. Information
Single pamphlet of 67 numbered paragraphs. The 'ghosts of departed quantities' phrase (§35) is the most-cited passage.
