P44 "It is of the nature of reason to regard things as necessary, not as contingent." (
It is this proposition which I will attempt to confront and the reason being is, it is opaque in nature, and rather abstract (to me of course). Spinoza is setting up an epistemological argument for reasoning and is comparing it to thinking based on contingency. On one scenario we have “the nature of reason” regarding things as necessary and the nature of reason NOT regarding things as contingent. Spinoza goes on to say that based on this claim we can make the further claim that when we conceive of something as contingent it is only because our imagination is acting upon what we perceive(Of the Mind; Dem 143). What Spinoza goes on to say in the scholium to proposition 44 is of huge importance in relation to this notion of necessity and contingency and their relation to the nature of reason. Spinoza says “…that if the human body has once been affected by two external bodies at the same time… when the mind imagines one of them, it will immediately recollect the other also…”(The Ethics On the Mind 143), we must start with what Spinoza is trying to say here. According to Spinoza, when people learn, or observe rather, two things which both occur simultaneously the mind, or rather the imagination, creates a correlation between the two. We can now approach Spinoza’s example regarding this; the boy who sees Peter, Paul, and Simon on various parts of the day learns to correlate their seeing of the particular person to the time of day, so based on temporality and the natural movement of time a particular person will come up when a particular time of day passes (On the Mind 143-144). This applies with anything not only temporality and people but also with standard habituation. In any psychology course they run Spinoza’s contingent experiment on their students, they will show you a picture of a dog then a cat then the same dog that showed up the first time, and the person watching this series of photos will safely assume that a cat will show up next, it is exactly this that Spinoza says is not the nature of reason. Spinoza continues with saying that “…this necessity of things is the very necessity of God’s eternal nature.” (On the Mind 144), So now Spinoza, in proposition 44, has not only created an epistemological theory but has correlated it with Spinoza’s own notion of God, which entails this notion of the nature of reason to be, in Spinoza’s perspective, the only right approach to knowledge.
