Ethics is something that has application to real life.
Ethics is considered a practical science because its object is not merely to present truths that they are to be known, but to present truths that are to be acted upon.
Ethics is considered a practical science because it has influenced other types of science. For instance, other types of sciences that deal with humans use ethical principles.
Medical ethics
No. While ethics have an affect on how we conduct scientific studies, it is itself a field covered by philosophy rather than science.
Ethics is usually a discussion in philosophy. However there is the interdisciplinary study of the philosophy of science, which has a branch that deals with ethics in science. Though not often noticed ethics is BEHIND science. Ethics is not science, it is the base of science. All the basics of Western Ethics are 1 to 1 copied to 'science'. The very basic of western ethics is presuming a mind body split. That means that PER DEFINITION reality is seen as sum of immaterial things (metaphysics) and material things (physics). Immaterial things are 'soul', 'mind', 'consciousness', 'understanding'. This assumption when related to 'soul' and 'spirit' is often called 'creationism'. Believing in 'consciousness', 'understanding', .. is not different at all, but now called 'rationalism'
