But here were books, and here were men who had penetrated deeper and knew more. I took their word for all that they averred, and I became their disciple. It may appear strange that such should arise in the eighteenth century; but while I followed the routine of education in the schools of Geneva, I was, to a great degree, self taught with regard to my favourite studies.
