Ethics Lab

An interactive philosophy playground exploring Consequentialism and Kantian Deontology.

Consequentialism

Consequentialism argues that the morality of an action is determined entirely by its consequences. The morally right action is the one that produces the best overall results for everyone affected.

Utilitarianism — a major version of consequentialism — evaluates outcomes based on total happiness and suffering.

Deontology

Deontology holds that morality is grounded in duties and rules rather than consequences alone.

Immanuel Kant argued that moral rules arise from the Categorical Imperative, which requires that we act only on principles that could become universal laws and that we treat persons as ends rather than mere means.

Interactive Moral Dilemma

A runaway trolley is about to kill five people on the tracks. You can pull a lever to divert it onto another track where it will kill one person instead.

Decision Visualizer

Consequentialist Reasoning

  • Calculate outcomes
  • Compare total happiness or suffering
  • Choose action with best net result
Example: Save five instead of one.

Kantian Reasoning

  • Ask if rule could be universal law
  • Respect persons as ends
  • Do not use people as mere means
Example: pushing someone may violate respect for persons.
