Epistemology and Simulation

Epistemology is the study of knowledge. What is knowledge exactly? Well, I’m happy (for reasons argued elsewhere) to use the definition going back to Plato, that of justified true belief. For example, I know – or at least believe – that there’s a tree growing outside my window.

Ultimately, this belief is grounded in the way the human visual system works, and on the way in which my perception of the tree triggers remembrance of trees past. All this falls within the scope of cognitive psychology, and experimental work in this area has told us a great deal about how human perception works.

Is my belief true? You’ll have to judge that for yourself (although the photograph may help convince you). Is it justified? Well, that’s the domain of philosophy – am I justified in trusting my senses?

In his Confessions, Saint Augustine takes “seven and three are ten” as a touchstone of truth, and in his City of God, he writes “the man who says that seven and three are eleven, says what cannot be true under any circumstances.” I agree with him. Here again, my belief falls within the scope of cognitive psychology (and developmental psychology, since Cuisenaire rods helped convince me of this back in kindergarten).

Seven and three are ten

Is my belief true? Once again, judge that for yourself. Is it justified? Well, that’s the domain of mathematics this time (and, as an older child, I learned to prove 7 + 3 = 10 mathematically).

Shortly, I hope to attend the 5th Epistemological Perspectives on Simulation (EPOS) Conference at Trinity University (San Antonio, Texas). We will be exploring whether it is possible to know things (especially things about social phenomena) as the result of a simulation (and, if so, how). It promises to be an interesting event. Papers from two of the four past instances of this conference series can be found here (2004) and here (2008).
