 The problem with this view, according to Nadler, is that “all that Garrett is warranted in concluding from his argument and the central passages in question is that degrees of consciousness and degrees of power of thinking in a mind vary proportionately, but not that consciousness is itself identical to power of thinking” (592–93). However, given Spinoza’s representational account of mind, the only two features that stand out as candidates for explaining consciousness are some features of the representations themselves (their complexity) or the causal efficacy of the ideas (their power).
