This is just something we have to agree on to get anywhere The universe operates according to understandable rules or laws. These laws are immutable.-They don't change based on who you are or when you are. These laws can be discerned, studied, and understood by people through careful observation, experimentation and research. The purpose of science is to simplify reality for us-to help understand and deal with it. The world, including the past is difficult to know, and requires discipline Feder raises the issue of deconstructionists, and in some ways it is a phony issue.
Science is a western way of knowing the world, and it is perhaps the west's greatest contribution.
It allows the substantial understandings of the world. The issue is phony because, it science is human form of knowledge, and it has its biases. Truth and validity are not the same thing, as Feder implies. Validity is contextual. Validity says that a way of knowing produces consistent results.
