commonsense and causality. This works for simple cases of everyday life and for Newtonian physics and mechanics, where simple and direct casual relation can be easily identified. But as the scientists found out, simple "cause and effect" breaks down in more complicated systems like statistical mechanics. Causality totally goes out of the window when we deal with motion, evolution, quantum phenomena etc. Historically, natural science always remained surrounded by mysteries, it only widens its horizon by pushing out mysteries beyond a new and a little wider horizon. New physics (quantum mechanics) and evolutionary sciences has now totally abolished causality, and turned the light of formal logic off, plunging natural science in to darkness and engulfing it with mysteries. Albert Einstein and modern theoretical physics, following Kant is trying to pull humanity out of this darkness and to understand reality by imposing on it, its subjective mathematical categories and the consistency of mathematics. These mathematical categories, like logical categories of Kant are the works of our minds. Our minds are so constructed that things must appear to us through these categories. Like Kant, appearance, experience and experimental results for natural science simply are "reminders" and "pointers" to these categories! I fully agree with you and futurehuman that a large part of the drive to do science derives from a mystical urge. The mystical urge is vital to the discipline. I do not think one can get anywhere with the history and philosophy of science unless one takes "psychology" into account. Scientific
