When solving problems: the older the problem, the older the solution. If you’re trying to learn how to drive a car or fly a plane, you should read something written in the modern age because this problem was created in the modern age and the solution is great in the modern age. If you’re talking about an old problem like how to keep your body healthy, how to stay calm and peaceful, what kinds of value systems are good, how you raise a family, and those kinds of things, the older solutions are probably better.
