  In 1922, Albert Einstein visited Paris and interacted extensively with an
illustrious section of the French academia. In overfilled sessions at the
Coll\'{e}ge de France and the Sorbonne, Einstein explained his theories of
relativity, and prominent physicists, mathematicians and philosophers listened,
debated, questioned and explored facets of relativity. The 1922 visit had its
echoes in the life and works of many who participated, particularly decisive
for Einstein and the philosopher Henri Bergson. This essay examines that
eventful visit, focusing on the physical and logical aspects of Bergson's
critique, with physics commentaries, linking prominent French physicists and
mathematicians Langevin, Painlev\'{e}, Hadamard, Becquerel, Sagnac, and
Kastler. I give particular attention to the logical and empirical accuracy of
the physics issues involved, delineating Bergson's exact reasoning for his
philosophical enthusiasm in Einstein's theory and for the ensuing critique.
Bergson's philosophical stand on duration and simultaneity is reassessed in the
context of later developments in cosmological physics as well as the wealth of
empirical data involving comparison of atomic clocks. Finally we are led
naturally to a surprising completion of the philosopher's program on universal
time, duration and simultaneity, in harmony with the time of the physicist. In
the appendices after the main text I also give the physics background and
easily verifiable proofs for the assertions made in the text, pertaining to
relativity, simultaneity and time dilation, clearly distinguishing beliefs and
facts.
