In shaping my theses I am committed to the principle of Occam’s razor. William of Ockham (1290 – 1349) was an English theologian and philosopher; the principle attributed to him,
based on economy of thought, states that one should only assume what is absolutely necessary. In other words, the simplest hypothesis is always preferable to more complex ones. To explain a fact, nothing should be accepted as necessary that does not rest on definite experience or clear logic, or that cannot be derived from articles of faith.
For example: the geocentric Medieval world view forced astronomers to carry out more and more complicated calculations in order to precisely predict the movements of heavenly bodies. According to the principle of Occam’s razor, the Copernican world view that places the sun at the centre is preferable to the geocentric world view, because it describes the same facts more simply and elegantly.
