The Origin of the History of Science in
op. cit., 168f., refers in this connection to Seneca (NQ VI,5.31, VII,25.
4–7, VII,30.5–6) and Pliny ( HN II,15.62); the latter seems to be influenced by Seneca. “Men who have made their discoveries before us are not our masters, but our guides. Truth lies open for all; it has not yet been monopolized. And there is plenty of it left even for posterity to discover.” (Sen. Ep. 33, 10, cf. 64, 7). It is debatable whether Seneca’s ideas were born out the experience of the previous progress in science and technology or derived from Posidonius. For an interesting discussion on this point and an ample bibliography, see Gauly, B. M. Senecas Naturales Quaes- tiones . Naturphilosophie für die römische Kaiserzeit, Munich 2004, 159ff. 63 Isocrates was born in 436; Archytas, probably about 435/430. 64 On similarities in the understanding of técnh by Isocrates and the author of VM, see Wilms, H. Techne und Paideia bei Xenophon und Isokrates, Stuttgart 1995. 3. Archytas and Isocrates 61 which was initially oriented toward practical knowledge, in his descriptions of mathematical disciplines as well: It seems that arithmetic (logistiká) far excels the other arts (tõn mèn @llãn tecnõn) in regard to wisdom (sofía), and in particular in treating what it wishes more clearly than geometry (gewmetriká). And where geometry (gewmetría) fails, arithmetic accomplishes proofs … (47 B 4). The terminology of this fragment deserves elucidation. Since it deals with demonstrations in which arithmetic surpasses geometry itself, what Archytas means by logistik2 is not practical computation but theoretical arithmetic, i.e., the theory of number based on deduction. Elsewhere he calls arithmetic simply @riqmoí, and the four mathematical sciences together maq2mata (B 1). In the fragment of the treatise Perì maqhmátwn, where the social role of arith- metic is discussed, it is called logismó~ (B 3). Is there any difference between logismó~ and logistik2, and does logismó~ refer, accordingly, to practical or theoretical arithmetic? Leaving this question open for a moment, let us note that Plato often uses logistik2 and @riqmhtik2 indifferently in this respect; 65 Aristotle also applies the new term, @riqmhtik2, and the old one, logismoí, to one and the same science. 66 The distinction between practical logistic and the- oretical arithmetic is first found in Geminus (Procl. In Eucl., 38.10–12); later it was taken up by the Neoplatonists, who attributed it, naturally, to Plato. 67 None of the passages of Plato usually cited in this context, however, suggests this meaning. This fact was pointed out and explained long ago by J. Klein, who showed that, in Plato, the difference between logistic and arithmetic comes down to the former referring mainly to counting and the latter to computation; both disciplines can be theoretical, as well as practical. 68 As the material of the fifth and fourth centuries shows, we can hardly expect the names of sciences and their classification to be rigorous and unambiguous. Neither is there any contradiction in the fact that Archytas treats arithmetic and geometry as mathe¯mata (B 1, 3), yet places them elsewhere among técnai (B 4). In his time, the mathe¯mata, though constituting, among other técnai, a special group, had not yet become model of ëpist2mh. Under the influence of the word-formative model of técnh, Archytas in one place even changes the traditional term gewmetría 69 into gewmetrik3 (técnh). 70 By “(all) other téc- 65 Res. 525a 9, Gorg. 451c 2–5, Tht. 198a 5, Prot. 357a 3, Charm. 165e 6, 166a 5–10. 66 Cf.

Chapter 2: Science as técnh: theory and history 62 nai” he must have meant not only mathematical sciences (he would have used the term maq2mata in this case), but also other occupations traditionally re- lated to this field. Owing to its sofía, arithmetic surpassed all these técnai, which Archytas considered from the cognitive point of view. In the context of técnai (crafts, poetry, music, medicine), sofía is usually understood as ‘skill, craftsmanship, artfulness’ and is often associated with ‘precision’ (@krí- beia). 71 Archytas transfers this quality from the master to técnh itself, thus making arithmetic appear more ‘artful’ and, hence, more ‘precise’ than all the other técnai, including geometry. Arithmetic surpasses the latter in ënárgeia, i.e., clearness, evidence, and obviousness, which makes it, in comparison, more demonstrative. 72 This quality of arithmetic is close to what the author of VM most of all required of medicine as a técnh: clearness and precision in knowl- edge (eıdénai tò safé~, katamaqe$n @kribéw~). 73 Isocrates, in his own field, held similar ideals: písti~ ënarg2~ and @pódeixi~ saf2~ are, for him, the key notions that characterize the conclusiveness of a statement. 74 Download 1.41 Mb.
