Artists, researchers, teachers...
The Synthesis team member works to align stringency with openness, knowledge with generosity. Certain are specialists, recognized in their particular domain; others come as sharers of their passions, as teachers of art or philosophy or are themselves recognized artists. Theatre, cinema, literature, singing, architecture, jazz, painting, symphonic music, neurology…a wealth of languages and viewpoints call out in an invitation to inspiration.

Matthieu Giroux



Following preparatory studies at the Hypokâgne and Khâgne levels, and majoring at the Lyon III University in French, Philosophy and Theology, he taught philosophy at the college prep level and again at university in accordance with the maxim ‘Better thought for better action’. In terms of his work for Synthesis, Matthieu Giroux helps managers to visualize and discern the meaning of the words and values expressed in business. His perspective on questions of time, courage, authority, and innovation allows a rapprochement within the managerial experience while avoiding the entanglements of language and of over-simplification. Philosophy is then experienced as a means of opening out and questioning oneself, which in turn lend force and precision to action.
