Which Philosophers Introduced Ethics?
As with many of the other branches of Philosophy that we have explored, discussions on Ethics in the Western world started with the Ancient Greeks. Since then, many ethical theories have been proposed by various thinkers over the centuries.
Generally, ethical theories are divided into three main schools of thought:
- NormativeDeriving from a standard or norm. Ethics: This focuses on general principles that help us decide how to behave and which actions to take.

As you may have guessed, Ethics focuses on questions about good and bad, right and wrong, and how to behave. This means that it considers important questions such as:
- What is the right thing to do in any given situation?
- What makes an action good or bad?
- What does it mean to live a good life?

Ethics helps us navigate the complexities of life and figure out how to live a good life, both as individuals and as part of a community. It gives us tools to navigate complex ethical questions and make moral decisions. It also offers a way to think about how we treat others and ourselves. All of these things are vital for a society to function.
