Abstract

Humans look at, think about, and manipulate things with tools.1 Some tools are largely pragmatic in nature, and they have a long history in our lineage, but more recently, humans have innovated tools for keeping track of features of the environment. Epistemic tracking tools (as I shall dub them) allow us to think, perceive and manipulate the world with a precision that we would otherwise lack. These epistemic tracking tools (henceforth ETTs) will be the focus of this chapter. ETTs track particular environmental variables examples of such tools include maps, compasses telescopes, sextants, and so on. There are also abstract systems of representation that track numbers, sets, sounds, and phonemes, and collectively as sets of propositions and equations can track physical phenomena, or perhaps even the truth. This chapter will focus on providing an account of the evolutionary platform for ETTs, look at some examples of ETTs in action and some of the consequences of the account for the extended knowledge literature.
