Some comments on the first draft

Here is one thing to think about:

We could have the definition "a bachelor is an unmarried man". Call this Bachelor_formal (as it is the formal definition). Assume it is a fine definition (assuming man and unmarried are defined). We could then discuss as to how much natural usage follows this definition (and there are many ways to measure this, usually with two numbers). And when we want to be careful we would specify whether we mean Bachelor_formal or Bachelor_common_usage. In science, it turns out that it is better to be precise, so that we more and more use planet_formal rather than planet_common_usage. Then, when we specify that Pluto is a planet_formal then we can measure the properties of Pluto and come to a conclusion (and perhaps even be unsure because we can't measure all of the properties of Pluto). When we want to determine whether Pluto is a planet_common_usage, then first it changes over time, and secondly it is more a question of sociology than of the properties of Pluto.

Thank you very much for the additional feedback and letting me know of the post. I will try to think over this question, relating philosophical talks to the scientific context. For now, I have to attend to the math assignment, which is falling apart :)
