imagination: contingency in the past or future

======= E2: PROP. 44:
It is not in the nature of reason to regard things as contingent, but as
necessary.
Proof.--It is in the nature of reason to perceive things truly (E2P41),
namely (E1A6), as they are in themselves--that is (E1P29), not as
contingent, but as necessary. Q.E.D.
======= Corollary 1.--Hence it follows, that it is only through our
imagination that we consider things, whether in respect to the future or the
past, as contingent.
