Abstract
In this paper I explore Peirce's account of association and his view that it is the only force which exists within the intellect. I look to the British Associationists, especially Hume, for the background. From there, Peirce's theory of attention becomes important for explaining the formation of associations. Finally, I argue that resemblance and contiguity are reduced to association by utility motivated by the individual's interests. Placing association in a general theory of the individual's interests is important for understanding the habits and critical self-control that are essential for the ultimate aim of the growth of concrete reasonableness.
