Mr. Anaxagoras, the conversation has escalated too much. I prefer to cut it here, sorry, your tone is unpleasant and disrespectful now. See you. For everybody, things I consider important on that conversation with Anaxagoras: - Both science, philosophy (or better, the different philosophies) and religion (the different religions) include or are knowledge systems, therefore including rules and based on axioms (see [3] for what I am calling an axiom).
- Unlike most philosophies and all religions, science uses exclusively reason, and that in a very specific way. This can be an advantage or a disadvantage. For example, due to this, science cannot make moral evaluations.
- Using reason includes using our perceptions, to derive (in this case: deduce) information. This way, we can deduce things, for example, that there is an objective universe, or that China exists. All these are asserts, deduced with reason (and subject to modification).
- The world as we percieve it using reason, is a world where reason is very effcient. However, this is not "proof" of the validity of reason as a whole:
- There cannot be such proof, as it would mean (proving = deducing correctly) using reasons outside reason.
- Everybody can, with a bit of effort, construct another system which shows a world, where that other system is very efficient and reaons is perfectly useless. I have made this as a joke in some Spanish forums, it is not very hard (about 1-2 hours). So... that a system shows us a world where this system is efficient, does not proove the system nor is it an exclusive characteristic of "reason".
- In a conversation, you can define an ant as "elephant" and then say that ants are mammals. There is no problem here, definitions are language conventions, and as long as the other one is informed about your redefinition, he can understand your sentence and then:
- Accept the redefinition for that context. - OR -
- Reject it and use the meaning ("elephant") or another word for it.
- Both are acceptable, none is a problem.
That's it. Nice talk, and goodbye.
