Teleological vs. Deontological — What's the Difference?

Difference Between Teleological and Deontological


Key Differences

Teleological ethics, also known as consequentialism, argues that the moral worth of an action is determined by its outcome. On the other hand, deontological ethics, based on the philosophy of Immanuel Kant among others, suggests that actions are morally right if they align with certain duties and rules, irrespective of the outcomes.
In teleological ethics, the ends justify the means—if the outcome brings about a greater good or beneficial results, the action is considered ethical. Whereas, in deontological ethics, the correctness of an action is paramount, and it must be done out of duty to moral law, even if it results in a less desirable outcome.
Teleological theories often focus on maximizing happiness or good outcomes for the greatest number of people, a concept central to utilitarianism, a prominent teleological view. On the other hand, deontological theories stress adherence to principles such as honesty, promise-keeping, and justice, regardless of the consequences.
The flexibility of teleological ethics allows for pragmatic decisions based on varying situations, making it adaptable but also sometimes unpredictable. Whereas, the rigid structure of deontological ethics provides consistency and predictability in moral judgments but can lead to dilemmas when moral laws conflict.
A teleological approach might sanction a morally dubious act if it leads to a beneficial result, such as lying to save a life. In contrast, a deontological approach would typically argue against lying, regardless of the positive implications, emphasizing adherence to truthfulness as a moral duty.
