This thesis project argues that Spinozism provides a useful framework for contemporary suicide studies. In Chapter 1, I provide an overview of the project and make some important preliminary notes. In Chapter 2, I develop a reading of Spinoza's philosophy of suicide which holds both that suicides are externally caused and that suicide may sometimes be rational, based on the very important discussion that Spinoza gives of Seneca's death. In Chapter 3, I explore the Spinozist implications of this view, showing that Spinozism demands that we make it so that suicide is never forced to be rational, and that this demands abolishing oppression. Though Spinoza is certainly not an oppression theorist in the contemporary sense of the concept, his discussion of a particular case of political repression lets us move to a view of oppression (contemporarily understood) as suicide inducing and thus in need of elimination. In Chapter 4, I explain two risks present in the three main models of contemporary suicidology. In Chapter 5, I illustrate the Spinozist framework's viability as an interpretive tool for suicide studies, with reference to three suicide notes, and explain how the Spinozist framework avoids the issues discussed in Chapter 4. In Chapter 5's conclusion, I emphasize on Spinozist grounds the need to abolish oppression and provide evidence to people that good living is possible."one who loves necessarily strives to have present and preserve the thing he loves" (E3p13s).
