Attempts by Avicenna and Ibn alNafīs to Expand the Field of the Transference of Demonstration in the Context of the Relationship Between Geometry and Medicine

This paper aims to deal with the disputes on transferring demonstration between various sciences in context of medicine-geometry relationship. According Aristotle’s metabasis-prohibition, these two should be located separate compartments due characteristics their subject-matter. However, a thorough analysis critical passage Posterior Analytics circular wounds forces revision boundaries interactions sciences, since subsequently Avicenna, grounds this passage, would widen area transference demonstration. Furthermore, fact that Avicenna and Ibn al-Nafīs continued use geometrical demonstrations anatomical investigations shows need understand kind-crossing prohibition as reminder take into account present scientific infrastructure logical rules before proceeding onto investigation instead accepting it mere nominal doctrine. Therefore, whether was possible or not depended extent which conclusion derived at end investigation, using different method after taking all reminders, had contributed solution particular proposition achievement an approximate truth.
