"Correct and accurate conclusions may be arrived at if we carefully observe the relation of the spheres of concepts, and only conclude that one sphere is contained in a third sphere, when we have clearly seen that this first sphere is contained in a second, which in its turn is contained in the third. On the other hand, the art of sophistry lies in casting only a superficial glance at the relations of the spheres of the concepts, and then manipulating these relations to suit our purposes, generally in the following way: — When the sphere of an observed concept lies partly within that of another concept, and partly within a third altogether different sphere, we treat it as if it lay entirely within the one or the other, as may suit our purpose."

“And O! how the mind is here washed clean of all its early ingrafted Jewish superstition! It is the most profitable and elevating reading which is possible in the world. It has been the solace of my life, and will be the solace of my death.”

“The New Testament, on the other hand, must be in some way traceable to an Indian source: its ethical system, its ascetic view of morality, its pessimism, and its Avatar, are all thoroughly Indian. It is its morality which places it in a position of such emphatic and essential antagonism to the Old Testament, so that the story of the Fall is the only possible point of connection between the two.”

“This art is music. It stands quite apart from all the others. In it we do not recognize the copy, the repetition, of any Idea of the inner nature of the world. Yet it is such a great and exceedingly fine art, its effect on man's innermost nature is so powerful, and it is so completely and profoundly understood by him in his innermost being as an entirely universal language, whose distinctness surpasses even that of the world of perception itself, that in it we certainly have to look for more than that exercitium arithmeticae occultum nescientis se numerare animi [exercise in arithmetic in which the mind does not know it is counting] which Leibniz took it to be.”

“And O! how the mind is here washed clean of all its early ingrafted Jewish superstition ! It is the most profitable and elevating reading which is possible in the world. It has been the solace of my life, and will be the solace of my death.”

“Change alone is eternal, perpetual, immortal.”

“In an essay on ‘“The Christian System,” he argued that the visions of the Old and New Testament are so unalike that the latter “‘must be in some way traceable to an Indian source: its ethical system, its ascetic view of morality, its pessimism and its Avatar, are all thoroughly Indian.””
