--- I have taught logic, and my students usually end up accepting, that if she had a child and got married she obviously got married and had a child. I have a bit more of a problem with Ryle's example, "He died, and drank the poison".
"But 'and' does not mean that"
Never mind what 'and' means. Stick to /\.
Socrates drank the hemlock /\ Socrates died.
Surely "<=>" with:
Socrates died /\ Socrates drank the hemlock.
This illustrates one aspect of Doctorow on 'the nature of causation' as per the essay he presented with M. Doctorow back in Berkeley in 1983 --.
Next lesson: What were the probabilities of Socrates NOT drinking the poison after his dying. Etc.
