The thought is a result of the past which uses the present as a passage to the future

The mind is a result of the past, which is based on time and its images.

Without the past there is no thought. 

But the thought, which is a result of the past, can't understand the present, since it only uses the present as a passage to the future.

The future is in this way always a becoming.

As Pascal claims, then the present is therefore never seized, though the understanding exclusively is lying herein.
