PSR, Nihilism, and Dialectic of Enlightenment

The dualization of nature as appearance and sequnce, effort and power, which first makes possible both myth and science, originates in human fear, the expression of which becomes explanation. It is not the soul which is transposed to nature, as psychologism would have it; mana, the moving spirit, is no projection, but the echo of the real supremacy of nature in the weak souls of primitive men

Horkheimer and Adorno, Dialectic of Enlightenment (p. 15)

In the next few posts I want to begin exploring the relationship between the PSR (Principle of Sufficient Reason) and our effort to make sense of our lives. The latter concern may seem to be a subset of the former – after all, if the PSR calls for an explanation for why things are as they are and not otherwise, then this would also include, apparently, an explanation that accounts for and explains our lives. This could not be further from the truth, however, as became increasingly apparent to many 18th century philosophers who began to think thorugh the implications of Spinoza’s rationalism, and its attendant reliance upon the PSR. In particular, many saw in Spinoza a nihilism whereby nothing in our life means anything but is simply that which follows from the necessity of God’s nature, and it is God’s infinite nature that explains, in the end, our existence. This explanation, however, does nothing to give meaning to our existence, or so the critics of Spinoza argued, and thus Spinoza’s reliance upon the PSR is not, on this view, in line with our effort to make sense of, and find meaning in, our lives.
