Abstract
‘One Science, One Method’ recounts Descartes' growing awareness of the unity under mathematics of many sciences that had previously been regarded as distinct. He became increasingly receptive to the possibility of a master science, or a master method of scientific discovery, that would have all the advantages but none of the drawbacks of the procedures followed in logic, algebra, and geometry. Descartes claimed in the Discourse on Method to have found such a method, and to have applied it with some success, but concluded that, since the principles of the other sciences depended on philosophy, in which he found nothing certain, he needed to establish certainties in that field.
