Explain what logically possible BACKWARDS time travel THAT TAKES TIME involves, according to Lewis.
Explain what logically possible BACKWARDS time travel THAT TAKES TIME involves, according to Lewis. Is the logical possibility of such time travel threatened by any of Bernsteins considerations about space? If you answer yes: focus on just one of Bernsteins three main considerations and explain why it threatens the logical possibility of backwards time travel that takes time (as Lewis conceives of it). Then explain whether Lewis must accept one of Bernsteins two final models of time travel that takes timeand if so, which one he should accept. If you answer no: explain, for each one of Bernsteins three considerations about space, why it does not threaten the logical possibility of backwards time travel that takes time (as Lewis conceives of it). Then explain whether Lewis should still accept one of Bernsteins two final models of time traveland if so, which one he should accept.
