I know they're all right, but you can't use a word with multiple definitions, can you? It'd be bloody impossible. It matters which tense you say them in; with philosophy it appears that multiple definitions of philosophy fit a similar tense.

2. If All H are M, S is H, then it means S is M.
3. You don't need to observe anything, you just need to use logic and reasoning.
4. An observation can be wrong, facts can't, not can logical deductions, by definition.
5. Also, not all rules have exceptions and logic and facts do exist.
6. When has logic ever stated something that isn't true?
I've numbered them so I can make my answers clearer.
1: But how do you find the facts?
2: Yes, A=B=C=D. Stop repeating it.
3: Logic is the "study of the principles of valid inference and correct reasoning". Of course, to apply this, you need to replace A, B, C and D with ideas, theories, call them whatever you like; they are collected from observations.
4: Facts can't be wrong, you're right; but what we believe to be facts can. Logic can be wrong; hence the existence of paradoxes.
5: Name one rule which absolutely cannot conceivably have an exception.
6: Read the unexpected hanging paradox.
