I watched the original "The Ascent of Man" series as a teenager in the early seventies & periodically caught up with sporadic episodes via video recordings & repeat broadcasts over the years.
Having purchased the DVD box set & had the chance to watch all 13 episodes in sequence over a short period of time, I have been nothing short of spellbound by a second exposure to Bronowski's achievement & performance.
This is material you need to immerse yourself in totally - close the door & brook no interruptions. Bronowski's greatest legacy through these essays is the way in which he brings to life through his own understanding & humanity the key individuals who have dominated the history of science. Each viewer will draw their own conclusions & have their own favourites, but for me the desciptions of the life & work of Alfred Wallace, Gregor Mendel, Albert Einstein & Leo Szilard are peaks on the already high plateau of analysis & explanation.
The series is peppered with profound quotations from his subjects & wonderful prose from Bronowski himself. I would challenge anybody with an ounce of humanity not to be moved by the closing sequences of 'The Majestic Clockwork','The Long Childhood' &, of course, 'Knowledge or Certainty' which is angry, chilling & heart-rending all at the same time.
They do not make them like this anymore.
