This passage is a long series of simply incredible misstatements. The history of chemistry and the lives of the adepts alike bear witness against it. My object in publishing this book is to establish the true nature of the Hermetic experiment by an account of those men who have undertaken it, and who are shewn by the plain facts of their histories to have been in search of the transmutation of metals. There is no need for argument; the facts speak sufficiently. It is not to the blind followers of the alchemists that we owe the foundation of chemistry; it is to the adepts themselves, to the illustrious Geber, to that grand master Basilius Valentinus, to Raymond Lully, the supreme hierophant. What they discovered will be found in the following pages; here it will be sufficient for my purpose to quote the views of a French scientist who has made a speciality of alchemy, and who is also a high authority on the subject of modern chemistry. “It is impossible to disown that alchemy has most directly contributed to the creation and the progress of modern physical sciences. The alchemists were the first to put the experimental method in practice, that is, the faculty of observation and induction in its application to scientific researches; moreover, by uniting a considerable number of facts and discoveries in the order of the molecular actions of bodies, they have introduced the creation of chemistry. This fact ... is beyond every doubt. Before the eighth century, Geber put in practice the rules of that experimental school, the practical code and general principles of which were merely developed later on by Galileo and Francis Bacon. The works of Geber, the ‘Sum of all Perfection,’ and the ‘Treatise on Furnaces,’ contain an account of processes and operations wholly conformed to the methods made use of to-day in chemical investigations; while Roger Bacon, in the thirteenth century, applying the same order of ideas to the study of physics, was led to discoveries which, for his time, were astounding. It is impossible, therefore, to contest that the alchemists were the first to inaugurate the art of experience. They prepared the arrival of the positive sciences by basing the interpretation of phenomena on the observation of facts, and openly breaking with the barren metaphysical traditions which had so long checked the progress of the human mind.”[B]
