Sören Stenlund was appointed professor of theoretical philosophy in 2000. He was Head of the Philosophy Department in Uppsala and a member of the Faculty Board for the humanities in the period 2001-2003. He has been Director of Graduate Studies in the Department of Philosophy and the coordinator of the seminar for theoretical philosophy until his retirement in 2008. During the fall of 2003, Stenlund was a resident fellow of SCAS.

Since his dissertation in 1972, Stenlund has published books and articles on various themes in the philosophies of language, logic and mathematics. Problems concerning the nature and history of philosophy, and the philosophy of culture, are other themes dealt with in Stenlund’s publications, some of which are available only in Swedish. He is currently working on philosophy of mathematics. Partial results have been presented at several international conferences, in particular at the Second “Middle Wittgenstein” Colloquium in Brotas (Brazil) in 2010, where Stenlund was one of the invited speakers.

作者站在後期維特根斯坦立場上進行細緻的概念研究，澄清橫跨語言哲學、心靈哲學、邏輯哲學和數學哲學的眾多概念混亂，批判一係列跟語言研究有關的專門的概念和方法由於其無視適用範圍而引發的哲學問題。這對百多年來哲學經常追捧專門科學的概念和方法，國內哲學界也不斷掀起科學化的衝動，無疑是很好的清醒劑。
