Scholars ubiquitously refer to the method εξ υποεσεως, introduced at Meno 86e1-87d8, as a method of hypothesis. In contrast, this paper argues that the method εξ υποεσεως in Meno is not a hypothetical method. On the contrary, in the Meno passage, υποεσις means “postulate”, that is, cognitively secure proposition. Furthermore, the method εξ υποεσεως is derived from the method of geometrical analysis. More precisely, it is derived from the use of geometrical analysis to achieve reduction, that is, reduction of a less tractable problem to a more tractable problem. As such, the method εξ υποεσεως does not by itself serve to solve problems.
