The most accurate guide for civilization, for life, for success, for everything on earth is science, it is knowledge. Looking for a guide other than science and knowledge is inattention, ignorance and heresy. However, it is a must to understand phases of development in science and knowledge in every moment we live and to keep up with progress timely. Attempting to employ rules set up by science and knowledge one thousand or two thousands or thousands of years ago just the same way today, after som ant thousans of years, is for sure not acting within parameters of science and knowledge.
