Surprisingly, both modern and traditional ethics are the faces of the same coin. So one should not try to antagonize them, but see them as they are not two contrasting values, but values linked and intertwined since the dawn of modern ethics. Modern ethics could very well be perceived as a logical, natural development spurred by traditional ethics. Since times change and there is nothing we can do about it, so do our ethical ideas and notions. What was wrong yesterday is right now, and what was right yesterday is wrong today. This happens because our thinking evolves, and even if we are living in a post-modernist era, it does not mean that ethics has lost its meaning. So always, keep in mind changing times when you think about ethical dilemmas.
Without philosophy, there would be no ethics, as ethics is one of the most important branches of philosophy. We are talking about the study of various values and customs of a person or a group of persons plus their use of different concepts, two of them being the concepts of what is right and what is wrong.
