Abstract | In this paper I take a close look at the SI base quantity “amount of substance”, and its unit, the mole. The mole was introduced as a base unit in the International System of Units (SI) in 1971, and there is currently a proposal to change its definition. I argue, first, that the current definition of the mole creates a certain ambiguity regarding the ontological status of “amount of substance”: is it a continuous quantity, like mass and length, or is it instead an enumerable aggregate? I then evaluate some of the criticisms this ambiguity has prompted. Finally I look at how the new proposal affects the ontological status of “amount of substance”. I conclude that while the new definition avoids the ambiguities of the older one, the mole still stands out among the base units of the SI. |
