Abstract

One can intentionally do something only if one knows what one is doing while they are doing it. For example, one can intentionally kill one’s neighbor by opening their gas stove overnight only if one knows that the gas is likely to kill the neighbor in their sleep. One can intentionally sabotage the victory of one’s rival by putting sleeping drugs in their drink only if one knows that sleeping drugs will harm the rival’s performance. And so on. In a slogan: Intentional action is action guided by knowledge. This essay reviews some motivations for a ‘knowledge-centered psychology’ — a psychology where knowledge enters center stage in an explanation of intentional action (§2). Then it outlines a novel argument for the claim that knowledge is required for intentional action (§3) and discusses some of its consequences (§§4-5)
