Excerpt from Six General Laws of Nature (a New Idealism): A Compendium of a Large Work "Divinity and the Cosmos", Containing the Primitive Cause of Force and Matter, an Explanation on All the Physical Phenomena in the Actuality of the Universe, and an Attack on the Modern Scientists and Philosophers
Introduction a few sentences from the letters of the leading philosophers of this country in reference to my MS. "Divinity and the Cosmos."
Professor William James, of Harvard University, to Prof. Edwin R.A. Seligman, of Columbia College.
"There is a spiritedness about his whole attempt, a classic directness and simplicity in the style of most of it, and a bold grandeur in his whole outlook, that give it a very high aesthetic quality, reminding me forcibly of Spinoza himself, opposed as are many of Silberstein's views to those of his great fore runner."
In his second letter to Prof. Seligman:
"There is really a grand style about his writing; quite a native kinship to Spinoza. In a letter to me Prof. James states: Your style is wonderfully spirited and direct at times, your attitude is noble and the simplicity of your outlook sublime. You are really a first cousin of Spinoza, and if you had written your system then, it is very likely that I might now be studying it with students just as Spinoza's now is studied."
Prof. Josiah Royce of Harvard:
"Your discussions, both of the history of philosophy and of the fundamental metaphysical problems, show, even in their fragmentariness, in the present Ms., an acuteness and skill that makes me wish that I could see in print your treatment of the fundamental question of philosophy. In this region your peculiar experience, your independence, your courage of conviction, produce results which reveal you in a very interesting light."
