Lacoste's influential 1994 book ''Experience and the Absolute'' argues against the modern prizing of "religious experience" and defends the view that God is knowable as lovable but does not give himself by way of experience or feeling.
In 2010, Lacoste delivered the James W. Richards lectures at the University of Virginia while he was a Visiting Professor of Religious Studies. His paper, "From Theology to Theological Thinking", called for erasing rigid distinctions between philosophical and theological disciplines.
