In 1765, Joseph Priestley created what may be the world's first modern timeline, A Chart of Biography. This paper offers the first study of the philosophy underlying Priestley's timeline. It argues that Priestley was pushed towards representing times as lines by his views on abstract ideas and time, and there is no reason to believe that Newtonian absolutism grounds his uniform depiction of time. Further, the Chart confirms, and even advances, Priestley's views on human progress. Finally, this study shows that (...) Priestley's conception of time as a line comprises a landmark contribution to the history of space-time parallelism. (shrink)

The Scottish philosopher Norman Kemp Smith (1872–1958) is best known for his 1929 English translation of Kant’s Critique of Pure Reason, and for his incisive commentaries on Descartes, Hume, and Kant. These achievements have overshadowed his original philosophical work in several areas, including the experience of time. A realist with idealist sympathies, Kemp Smith developed a non-transcendental version of Kant’s conception of time as a ‘pure intuition’ (though he insisted that temporal perception involved ‘categories’). He employed this conception to solve (...) a problem that was widely discussed in early twentieth-century European and American philosophy, which William James dubbed the ‘specious present’: how can we perceive an extended duration, like a full golf swing, or the cadence of a brief tune, if we only perceive the present? A closely related problem: if we only ever perceive the present, how can we distinguish among the future, present, and past? In this paper, I explain Kemp Smith’s proposed solution, and compare it with two of his contemporary influences: Samuel Alexander and George F. Stout. Finally, I suggest that these problems are still with us, and are likely to be for some time, especially if we ignore the insights offered by earlier discussions. (shrink)

This paper explores a trans-Atlantic clash about time: in 1899, American philosopher Mary Calkins argued we should not spatialize time; in 1899, British philosopher Victoria Welby argued we should. I take their disagreement as a starting point to contextualize, study, and compare the accounts of time presented in their respective articles. Both Calkins and Welby cared deeply about time, writing on the topic across their careers, but their views have not been studied by historians of philosophy. This is unfortunate, for (...) I argue their novel theories reward attention. Calkins’ 1899 account draws on Kant to arrive at the earliest American-British causal theory of time, pioneers the metaphysical applications of temporal experimental psychology, and replies to F. H. Bradley’s proclamation that it is ‘impossible’ to explain the appearance of time. Meanwhile, I read Welby’s 1907 account as offering a radical metaphysic, on which time is literally a kind of space, resonating with 1880s literature around the ‘fourth dimension’ and H. G. Wells’ 1895 novel The Time Machine. I have uncovered an early draft of Welby’s paper dating to 1902 and, using this alongside other unstudied writings by Welby, trace the development of her views from the 1880s onwards. (shrink)
