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

In modern socio-economic conditions, one of the priority areas of higher education is the training of a competent specialist with a high culture of thinking, capable of independently making responsible and professional decisions, and acting creatively in non-standard situations. Haber argues that critical thinking (hereafter – CT) is an indispensable skill to achieve this goal; moreover, current global burning issues point out that ‘acquiring and applying this skill is vital to our survival as a society’ (xiii). So, Haber presents his (...) book as a guide for educators, students, as well as for everyone who wants to reinforce his reasoning abilities (xviii). However, taking into account that in recent decades, hundreds of valuable textbooks, guidelines were written on CT, one may ask how Haber is going to avoid his book from being sunk in the ocean of this literature, and what kind of characteristics make it special from other books on this topic.
