As their greek predecessors, mathematicians and arab-speaking philosophers raised several important epistemological questions. One of those questions concerns the concept of equality and the concept of congruence of geometric magnitudes. What was the meaning of such concepts? How were they related to the idea of movement? Answers to these questions were often combining metric elements and other, philosophical (topological) elements, and I chose to study those of a mathematician, of a philosopher, and of a mathematician-philosopher.

作为他们的希腊前辈，数学家和讲阿拉伯语的哲学家提出了几个重要的认识论问题。其中一个问题涉及平等的概念和几何量级的全等概念。这些概念的含义是什么？它们与运动的概念有什么关系？这些问题的答案通常是结合度量元素和其他哲学（拓扑）元素，我选择研究数学家、哲学家和数学家-哲学家的那些。
