Abstract: In the Philosophy of Mathematics is a recent trend that objects to the previous one-sided focus on discussions on the foundations of mathematics and its ontology. They wish instead to pay more attention to the ‘practice’ of mathematics. In the talk I present some examples from this field referred to as ‘The Philosophy of Mathematical Practice’ and explain what is meant by ‘practice’ in these cases. I give examples of studies on the foundations of mathematics from a practice point of view as well as some of my own contributions to the role of diagrams in mathematics. The talk is based on my paper ‘The Philosophy of Mathematical Practice – Motivations, Themes, and Prospects’ from 2019.
