Applied Ethics is the third major field of ethics. It is the practical application of normative ethical theories (like Utilitarianism, Deontology, Virtue Ethics) to real-world, controversial moral problems.
This unit focuses on two specific areas: Environmental Ethics and Theories of Punishment.
Environmental Ethics is the branch of applied ethics that studies the moral relationship between human beings and the natural environment.
The central question is: Do we have moral obligations to the environment? If so, why?
This leads to a spectrum of views, with two main opposing poles:
This is a branch of social and political philosophy that asks: What is the moral justification for the state to punish criminals?
Punishment (e.g., prison, fines) involves intentionally inflicting harm, pain, or loss of liberty on a person. This requires a strong moral justification. There are three main theories.
| Theory | Core Principle | Justification | Guiding Slogan | Proponent |
|---|---|---|---|---|
| 1. Retributive Theory | Punishment is justified because the criminal deserves it. It is about justice and "paying back" the debt to society. | Backward-looking. Based on the past act. The punishment should be proportional to the crime (Lex Talionis). | "An eye for an eye." | Immanuel Kant |
| 2. Deterrent Theory (or Preventive) | Punishment is justified because it prevents future crime by instilling fear. | Forward-looking. Aims to create a better society by deterring crime. It is a Utilitarian justification. | "Make an example of him." | Jeremy Bentham |
| 3. Reformative Theory (or Rehabilitative) | Punishment is justified because it D_reforms** or rehabilitates the criminal. | Forward-looking. Focuses on the criminal, not the crime. The goal is to "cure" the criminal of their deviance through education, therapy, or vocational training. | "Treat the criminal, not the crime." | Modern Criminology |
