Of Suicide

Hume's essay "Of Suicide" presents one of the most systematic philosophical defenses of the moral permissibility of suicide, challenging centuries of Christian theological condemnation. Writing in an intellectual climate where suicide remained both legally criminal and religiously damned, Hume constructs a rationalist argument that directly confronts providentialist assumptions about divine sovereignty over human life.

The essay's central strategy involves dismantling three principal objections to suicide: that it violates our duty to God, to our neighbor, and to ourselves. Against the first and most substantial charge, Hume deploys his characteristic naturalism. He argues that if God governs through natural laws, then human actions, including suicide, cannot truly contravene divine providence. Every human act occurs within the causal order God established; therefore, suicide no more usurps divine prerogative than does saving a life through medicine. Hume pointedly notes the inconsistency in claiming that preserving life through human intervention is acceptable while ending it is not, when both equally involve human agency operating within natural laws.

The philosophical significance of Hume's argument extends beyond the specific question of suicide to broader issues in natural theology and ethics. By treating suicide as a test case, Hume exposes what he sees as arbitrary religious restrictions lacking rational foundation. His approach exemplifies Enlightenment challenges to revealed religion's authority over moral questions, insisting instead that ethics must answer to reason and human welfare.

Hume's treatment of duties to society and self proves equally subversive of conventional Christian ethics. He argues that individuals may reasonably conclude their continued existence brings more harm than benefit, both to themselves and others. This utilitarian calculus directly opposes Christian doctrines about the sanctity of life and the virtue of suffering. The essay thus participates in the broader Enlightenment project of constructing ethics on secular, rational foundations rather than theological commands.

The work's contribution to debates about God lies in its implicit critique of providentialist theology and divine command ethics. While never explicitly denying God's existence, Hume's argument renders divine will irrelevant to moral reasoning about suicide. This marginalization of theological considerations in ethics represents a crucial move in the secularization of moral philosophy, demonstrating how rational ethics might proceed without reference to divine commands or purposes.
