ABSTRACT
This chapter will begin its course by taking up the work of Gabriel Tarde on the economy, but as a signpost to what is occurring in the present. In other words, I will use Tarde as a staging post in a longer and more involved history of what I will call propensity, understood jointly as both a tendency-cum-attraction and an innate implication, that is, as a disposition to behave in a certain way which is only partly in control of the agent.
