Nothing is less Greek than the conceptual web-spinning of a hermit—amor intellectualis dei—after the fashion of Spinoza. - Benedictus de Spinoza

It is not possible, I think, to rise from the perusal of the arguments of Clark and Spinoza without a deep conviction of the futility of all endeavors to establish, entirely à priori, the existence of an Infinite Being, His attributes, and His relation to the universe. The fundamental principle of all such speculations, viz. that whatever we can clearly conceive, must exist, fails to accomplish its end, even when its truth is admitted. For how shall the finite comprehend the infinite? Yet must the possibility of such conception be granted, and in something more than the sense of a mere withdrawal of the limits of phænomal existence, before any solid ground can be established for the knowledge, à priori, of things infinite and eternal.

He [Spinoza] does not prove the existence of God, existence is God. And if for this reason others would brand him Atheum then I would praise him and call him theissimum and christianissimum. [Original in German: Du erkennst die höchste Realität an, welche der Grund des ganzen Spinozismus ist, worauf alles übrige ruht, woraus alles übrigefliest. Er [Spinoza] beweist nicht das Daseyn Gottes, das Daseyn ist Gott. Und wenn ihn andre deshalb Atheum schelten, so mögte ich ihn theissimum ja christianissimum nennen und preisen.]

Let him who wishes weep bitter tears because history moves ahead so perplexingly: two steps forward, one step back. But tears are of no avail. It is necessary according to Spinoza's advice, not to laugh, not to weep, but to understand!
