Ian Hacking is University Professor Emeritus at the University of Toronto. He holds the chair of Philosophy and History of Concepts at the College de France. Among his many books, the most recent is Rewriting the Soul.
[Hacking] focuses on the interactions between what there is (or comes to be) and our concepts thereof. The kinds of objects he considers, both of which he regards as historical, are Aristotelian universals and their instances. He emphasizes that not only do ordinary physical objects and people and their institutions begin, develop, and end, but so do concepts, e.g., those language, knowledge, a child, (psychic) trauma, and scientific reasoning...Stimulating, incisive, and clear even in expounding theories of unclear writers. -- Robert Hoffman Library Journal 20020415 What, asks Ian Hacking in Historical Ontology, do I mean by live skepticism? His answer is that it is desirable to be 'genuinely in doubt and terrified that one's doubt might be warranted.' It's a healthy position for an enquirer into how new concepts and objects emerge in the province of philosophers and inventors, the novel uses of words and new ways of reasoning, and new interplays of power and knowledge. His essays demand attention and close reading. -- Maggie McDonald New Scientist 20041106
