 From these passages, Nadler concludes that “human or higher consciousness for Spinoza is nothing but the mental correlate of the superlative complexity of the human body” (587). The result is that consciousness, for Spinoza, is a matter of degree (as is suggested in the passage above). Nadler also suggests the possibility that this could be a threshold concept—that there is a minimum degree of complexity that must be satisfied before a mind could be conscious. But, citing Garrett’s appeal to Spinoza’s naturalism, he dismisses the threshold view. And so, consciousness comes in degrees, and all minds have it (contrary to the worries in the ideae idearum  section).[11]
