One of the principal architects and advocates of Open Access to Research, for which he was accorded an honorary doctorate by the University of Liège, Harnad is vegan and an ardent advocate for electronic surveillance of the treatment of animals in industry and for Open Access to the data. He was the French-language spokesman in Montreal for the worldwide March Against Slaughterhouses June 13 2015. His first HP article is based on a translation of the talk he gave at that event.
On June 13 2015, all around the world -- in Paris, Brussels, London, Berlin, Istanbul, Delhi, Los Angeles, Toronto, Montreal -- people gathered to March for the Closing of the Slaughterhouses. But the slaughterhouses will not close of their own accord. To close the slaughterhouses people's eyes and hearts have to be opened.
