“… My view is also not entirely unfriendly to commentators such as Domski () who considers her approach opposed to a methodological one. For example, one might use the method to explain why the focus on intelligibility and constructability that Domski sees in Descartes’ classification of curves in the Geometrie and later in Le Monde even arises and in what sense they may or may not be related.…”

But I am engaged in a different project than commentators such as Domski ; who are looking to see what his mathematical problem‐solving techniques can tell us about his subsequent philosophical views. Even commentators such as Grosholz ; Grosholz and Hintikka who explicitly look at Descartes’ “method” are starting with mathematical methods.…”

“…Two examples are enough to explain why. Domski (Domski (2009), 123) emphasises the role played in Descartes' geometry by "a standard of intelligibility grounded on simple and clearly conceivable motions", and suggests that geometrical curves are those that can be obtained through an "intelligible motion". Arana (Arana (Forthcoming)) suggests, instead, that for Descartes "constructed objects are known best when the construction is carried out in a way that is fully present to the attentive constructing mind".…”

“…The case of Villalpando's locus and compass provides an example. Descartes seems to think of a situation like this when he alleges to have "furnished a way to describe" a curve, by "having explained the way of finding an infinite number of points though which" it passes, and adds that "this way of finding a curve by finding several of its points at random applies only to those curves which can also be described by a regular and continuous motion" (Descartes (1637), 339-340; Descartes (AT), VI, 411-412;Bos (2001), 344-345;Domski (2009), 125-129). One could then conclude that generic point-wise constructions of a curve are admitted by Descartes if and only if the curve is also traceable by a geometrical linkage suggested by the very construction.…”
Section: Descartes On Non-elementary Constructionsmentioning
A crucial concern of early-modern geometry was that of fixing appropriate norms for deciding whether some objects, procedures, or arguments should or should not be allowed in it. According to Bos, this is the exactness concern. I argue that Descartes' way to respond to this concern was to suggest an appropriate conservative extension of Euclid's plane geometry (EPG). In section 1, I outline the exactness concern as, I think, it appeared to Descartes. In section 2, I account for Descartes' views on exactness and for his attitude towards the most common sorts of constructions in classical geometry. I also explain in which sense his geometry can be conceived as a conservative extension of EPG. I conclude by briefly discussing some structural similarities and differences between Descartes' geometry and EPG.Une question cruciale pour la geométrieà l'âge classique fut celle de décider si certains objets, procédures ou arguments devaient ou nonêtre admis au sein de ses limites. Selon Bos, c'est la question de l'exactitude. J'avance que Descartes répondità cette question en suggérant une extension conservative de la géomètrie plane d'Euclide (EPG). Dans la section 1, je reconstruis la question de l'exactitude ainsi que, selon moi, elle se présentait d'abord aux yeux de Descartes. Dans la section 2, je rends compte des vues de Descartes sur la question de l'exactitude et de son attitude face au types de constructions plus communes dans la geométrie classique. Je montre aussi en quel sens sa geométrie peut se concevoir comme une extension conservative de EPG. Je conclue en discutant brièvement certaines analogies et différences structurales entre la geométrie de Desacrtes et EPG.
