A Momentary Lapse Of Reason Olga Grigoriadou Abstract: A Momentary Lapse Of Reason Comparing Davidson's account of rationality and reasoning to that of van Lambalgen & Stenning Olga Grigoriadou Abstract: I examine and compare two accounts of rationality and logical reasoning: that of Donald Davidson on the one hand and that of Michiel van Lambalgen and Keith Stenning on the other. My first aim is to examine the differences between these two theories, and the criticisms that each account can bring against the other. My second aim is to explore how a combination of the two accounts might result in a more complete account of rationality and logical reasoning than what is offered by either one alone. I conclude that the two accounts, although they at first seem to differ entirely from each other, have much in common, and that there are important elements in each that might be useful for the other (e.g. Davidson's Principle of Charity, or the distinction between reasoning to and from an interpretation introduced by van Lambalgen and Stenning). A combination of the two accounts may also have interesting implications for research in the field of education.
