First Published in 1987. This book explores the implications of Henri Bergson''s philosophy for contemporary science, discussing the misinformed view that Bergsonism stands for a romantic revival of anti-scientific vitalism notwithstanding. Likewise, this study draws value in that Bergson''s philosophy appears to offer guidelines as to how to restore paradigmatic cohesiveness between modern physics and the life sciences. The authors argue that Bergson''s ideas stand a better chance of being appreciated and their heuristic value harnessed today because the infra-structure alluded to before, is now in place.
