... same thing you would do with any axiom - it's a starting point from which other logical statements can be derived:
- "I experience, therefore I am"
- "I am, but I also experience other, therefore there is a reality distinct from I"
- "I am, and there is a reality distinct from I, but I have also experienced a method for successfully predicting future events in that reality, therefore the scientific method is a valid path toward knowledge"
- "I am, and there is a reality distinct from I, and the scientific method is a valid path toward knowledge, therefore ... ... ..."
... obviously, the logical statements above are completely notional (to get from "I am" to "science is a valid path toward knowledge" in just three logical steps is ludicrous), but I hope you get the gist.
Also note that I am not saying that every possible logical statement you can derive from "I am" can be related to the real world - any more than E=MC^3 can be related to real physics or 1 + 1 = 2 can be related to real water droplets ... logic and mathematics are human constructions for mechanizing a selection of hard-won human intuitions about the world we live in ... but as the water droplet case clearly demonstrates, any isomorphism between these mechanized intuitions and the real world must be experientially/experimentally demonstrated before being accepted.
