The excerpt represents the core issue or deciding factor on which you must meditate, and is drawn from Reason Discourse by Rene Descartes: establishes what he has advanced respecting the motion of the blood, from
the existence of certain pellicles, so disposed in various places along
the course of the veins, in the manner of small valves, as not to permit
the blood to pass from the middle of the body towards the extremities, but
only to return from the extremities to the heart; and farther, from
experience which shows that all the blood which is in the body may flow
out of it in a very short time through a single artery that has been cut,
even although this had been closely tied in the immediate neighborhood of
the heart and cut between the heart and the ligature, so as to prevent the
supposition that the blood flowing out of it could come from any other
quarter than the heart.
