Key Differences
Deontology and Teleology are two primary ethical theories. Deontology is grounded in the belief that morality is determined by rules and duties. In contrast, Teleology holds that the moral value of an action is determined by its outcome or purpose.
Deontology asserts that certain actions are inherently right or wrong, irrespective of their outcomes. Teleology, however, would argue that the morality of an action is based on the goodness or badness of its results.
In the realm of Deontology, individuals have moral duties to act in specific ways, even if it might lead to less favorable outcomes. For Teleology, the end justifies the means, and actions are morally permissible if they result in the best possible outcome.
Deontology often is associated with the philosopher Immanuel Kant, who believed in duty-based ethics. In contrast, Teleology finds its roots in utilitarianism, where the focus is on maximizing happiness or pleasure.
At its core, Deontology emphasizes the importance of adhering to moral rules, while Teleology evaluates actions by their consequences or final purposes.
