The Philosophers and Mathematics is an international colloquium organised by Hassan Tahiri, Center for the Philosophy of Science of the University of Lisbon, that takes place on 29th and 30th October 2014, at the Faculty of Sciences of the University of Lisbon, under the FCT research project Argumentation and scientific change. A case study of how Ibn al-Haytham al-Shukuk changed the course of Astronomy forever.


The Colloquium is organised in honour of Prof. Roshdi Rashed.

rashed2“Science is universal. This is not a postulate, but a basic feature which defines scientific knowledge itself. A scientific result, of whatever kind, can only be fully communicable and provable by stringent arguments. But this epistemic universality is not at all separate from the living history of human beings and from institutions. That is to say that this universality is not an immediate given of the consciousness, but rather reveals itself through a lengthy and bold conceptual process. This work organises itself along the lines of scientific traditions in which human beings and institutions are active. But these people and these institutions arise from a value-based system.”


“Historic objectivity is the result of a long, meticulous and critical research.” – Roshdi Rashed


Several years ago, Prof. Kokiti Hara, a leading historian of mathematics in Japan, once stated his observation to me: “The most productive field of history of mathematicsfor the past quarter century was without doubt the history of Arabic mathematics. “He added to this statement: “Thanks mainly to Mr. Rashed.”
