Source: p 120, Philosophy: A Complete Introduction (2012) by Prof Sharon Kaye (MA PhD (Philosophy), U. Toronto). The following question appears in Chapter 8 entitled Hume and causality.
- Which of the following is entitled to believe in laws of nature?
a) Empiricists b) Rationalists c) Materialists d) Idealists
[p 7, see also p 12 :] The view that the material world around us is not real is called idealism.
[p 64, cp. p 73:] The fundamental theme in Descartes's philosophy is reason: we discover innate truths through the power of clear thinking. In his hands, the inward-looking approach we have seen running through Plato and Anselm becomes the epistemology known as rationalism.
p 219 states (b) as the only answer with no explanation. I understand why (b) is an answer (as Laws of Nature supply reasons for truths), but why is (d) incorrect? I can imagine an Idealist who tries to understand the world by relying on Laws of Nature using maths and physics, because she has already adjudged the material world unreal and unreliable.
This website asserts the following which would vindicate (d):
Actually, the idealistic concept of the material world is logically compatible with the scientific view of matter. Idealism does not say that the natural world is unreal; it does not say that the laws of nature are mere inventions of the human mind; it does not say we can change the world magically by thinking differently.
