His [Hegel's] early and decisive break with theism came in correspondence with Schelling and Hölderlin, who were reading Fichte's 1794 Wissenschaftslehre as Spinozism on a Kantian foundation. He later professes his own Spinozism in bold terms. "You are either a Spinozist or not a philosopher at all” and "It is therefore worthy of note that thought must begin by placing itself at the standpoint of Spinozism; to be a follower of Spinoza is the essential commencement of all Philosophy. For as we saw above, when man begins to philosophize, the soul must commence by bathing in this ether of the One Substance in which all that man has held as true has disappeared”.
