The harbor gazette will write about it,
therefore a ship will sink off the coast.
Invalid argument because 'if X happens then Y does happen", as a premise, isn't fulfilled with 'X will happen'.
I see what you're saying, but I don't think the future tense indicated by "will" makes a difference here. The term "writes" seems to signify a future action in this case even if it's a present verb. If the first premise had "wrote" or "is writing", then I'd agree.
Quote:Premise 1: If a great many fossils and DNA evidence is found then evolution is very probably true.
Premise 2: A great many fossils and DNA evidence is found---but God put them there to test our faith.
Conclusion: Therefore, evolution is very probably true.
I say it's valid, despite the "but God" bit. Correct? It's a tricky one for me.
P1: If it is inevitable that I will do X, then I will do X.
P2: It is inevitable that I will do X
C: Therefore, it is a necessary truth that I will do X.
