The Origin of the History of Science in
part of fragment B 3 deals with the practical art of calculation does not prove that Archytas was consistent in drawing a distinction between logismó~ as the practical part of arithmetic and logistik2 as its theoretical part. 115 Emphasiz- ing the utility of the art of calculation, he might equally as well have used the term logistik3 técnh, which, like logismó~, could denote both practical and theoretical arithmetic. Turning to the traditional subject of the utility of a técnh does not imply that the técnh itself is regarded as practical. The usefulness of mathe¯mata for society was acknowledged even by Plato, 116 who saw their main value elsewhere. Aristotle, ascribing in his Protrepticus an independent value to theoretical knowledge, did not, however, fail to point out that philosophy could well prove useful in practical affairs as well. 117 The fact that mathematics and philosophy have an applied aspect does not undermine their status as the- oretical disciplines. Archytas, of course, could not fail to see the difference between the theor- etical and the practical aspects of the mathe¯mata, nor to realize that one and the same term, for example @strología, denotes both a mathematical science and applied knowledge used by sailors and farmers. This difference was obvious, at any rate, even for such a layman in mathematics as Xenophon. Speaking of So- crates’ attitude toward astronomy, geometry, and arithmetic, he notes that the latter recommended limiting oneself to the practical part of each of these sciences, without going deeply into theory ( Mem. IV,7.1–8). Hence, one does not need different terms to distinguish between a theoretical discipline and its applied counterpart. Though we do find in Archytas a new term, ârmonik2, de- noting, unlike mousik2, the science of music, 118 mousik2 is also repeatedly used in the same treatise for the science of music (B 1–2). Philip of Opus ob- serves that a theoretical science bears the ‘ridiculous’ name of gewmetría ( Epin. 990d 2), associating it with measuring land; the new term, gewdaisía, denoting the practical discipline, appears later in Aristotle’s Metaphysics (997b 26f.). 119 115 It is contradicted by the usage of Isocrates, Plato, and Aristotle, who referred lo- gismoí to theoretical arithmetic (see above, 61 n. 65–66). 116 Res. 522c, e, 526d, Leg. 809c–d. 117 Fr. 46, 51, 54 Düring; EN 1172b 5f., 1177a 32–b 4. Elsewhere he stresses again: though theoretical sciences like astronomy or geometry may prove to be useful, their main purpose is knowledge ( EE 1216b 11f.; cf. Isoc. Antid. 262–269, Panath. 30–32). For the same in Proclus, see In Eucl., 25.18ff. 118 Archytas’ treatise on the theory of music was entitled ˆArmonikó~ (B 1), but whether it was he who coined the term remains uncertain. In Aristoxenus ( Harm. I, 2, 5, 7 etc.), the word ârmonikoí denotes a trend in the fifth-century harmonics; ac- cording to the papyrus Hibeh 13 (col. I,4) this was a self-definition. 119 Aristotle also pointed out that different disciplines could bear the same name: sce- dòn dè sunønumoí eısin Éniai toútwn tõn ëpisthmõn o‰on @strología 6 te maqhmatik3 kaì 1 nautik2 (APo 78b 39). Though he means here a theoretical Chapter 2: Science as técnh: theory and history 74 Isocrates, speaking about Busiris’ invention of philosophy, which included astronomy, geometry, and arithmetic, observes that some praise the utility of these sciences, while others attempt to demonstrate that they are conducive in the highest measure to the attainment of virtue. 120 Though the rhetorician does not state his attitude toward these views directly, his silence seems to indicate that he does not share them. 121 Among those who did hold both these views, one ought, first of all, to cite Archytas, who praised the practical utility of mathe- matics and its ability to improve moral qualities. 122 It is revealing that Download 1.41 Mb.
