Abstract

Comparisons that have been made between the philosophies of Martin Heidegger and Bernard Lonergan on such topics as transcendence, authenticity, and the inadequacies of substance metaphysics are justified, but they must be understood against the background of a disagreement over the meaning and role of ontological difference. A reading of Heidegger that emphasizes the negative or recessive aspect of the ontological “lighting” or “clearing” in being puts this disagreement into sharp relief and forms a charge against Lonergan of “forgetfulness of being.” A response to the charge is offered in the form of three approximations, focusing, respectively, on the way that Lonergan uses the term, “intelligibility,” the role he gives to question, and the way he finds ontological significance in a particular range of intentional acts.
