I understand the concept of logical consequence, for example:
1.All persons are human
2.I am a person
Conclusion: I am human.
If 1 and 2 are true, conclusion must be true.
My question is about
would this be a logical truth for example?
- My name is Drx
- Drx is batman
conclusion: 100 = 100
As I understand it the conclusion is true no matter what the premises are. But my definition says:
A logical truth is a sentence that is a logical consequence of any set of premises. That is, no matter what the premises may be, it is impossible for the conclusion to be false.
Is the conclusion above really a logical consequence of its premises even when the premise doesnt have anything to do with the conclusion?
Sorry if this got confusing, if the above is not a logical truth please give me an easy example :D
