Utilitarianism vs. Deontology: What's the Difference?

Edited by Harlon Moss || By Janet White || Published on November 24, 2023
Utilitarianism is a moral theory that advocates actions maximizing happiness for the most people, while deontology focuses on the morality of actions themselves, regardless of consequences.

Key Differences

Utilitarianism judges actions based on their outcomes, specifically aiming to maximize overall happiness or utility. In contrast, deontology evaluates the morality of actions based on a set of rules or duties, regardless of the outcome.
Utilitarianism involves a consequentialist approach where decisions are made based on the potential results of an action. Deontology, however, follows a duty-bound approach, where decisions are made based on moral obligations and principles.
Utilitarianism offers flexibility as it considers the context and consequences, allowing for varying moral decisions in different scenarios. Deontology is more rigid, adhering strictly to moral duties and rules without considering the situation's specifics.
In ethical dilemmas, utilitarianism would prioritize the greater good, potentially sacrificing individual rights for collective happiness. Deontology would uphold individual rights and moral principles, even if it leads to less overall happiness.
Utilitarianism is often criticized for potentially justifying harmful actions if they lead to a greater good, while deontology can be seen as impractical or overly rigid in certain situations.
