Beautiful meeting, not really unexpected, two people I admire and love through it. JM Pelt develops an interesting observation which could explain the évolution.Ce that gives new light on his uncertain theories attempting to explain the improbable "big bang" to our contemporaries "explosives"! P. Rabhi resumes his theses with a pleasant persistence. A book that makes time travel and well anchored in the modern world. A book that gives arguments to people of good will, against all forms of extremism and barbarians approximations. Salutary.
