I think chapters 5-10 are the heart of volume one. Chapters 11-15 deal with further interesting notions. Note also that each chapter has specific elements that contribute to a manifold argument (i.e. each chapter seems to try to blend the first four elements), a very ambitious project:
1- Comparing, critiquing and contrasting ancient and modern science (and rehabilitating the former);
2- Comparing ancient and modern western knowledge with eastern culture;
3- Using the first two points (with wider comparative research) to posit the existence of a universal, perennial wisdom;
4- Using the first 3 points to introduce notions of esoteric philosophy;
5- Using these notions of esoteric philosophy to build a new synthesis of (a)ancient and modern science; (b) eastern and western knowledge; (c) science and religion.
6- Arguing for the idea of India as the cradle of civilization.
7- Critiquing and clarifying spiritualistic phenomena.
