Sweetchic: ok, I will repeat it once more... If you call natural science "proper", when by contrast one assumes social science is "not proper", which is obviously an incorrect assumption. No one is denying that natural science is different from social science, but to call one "proper" is to make the other "not proper" - by contrast. About being creative / imaginative: it's funny, because my dictionary says, creative: imaginative; imatinative: creative. At root level they're different, as one is often used to refer to constructions of the mind (imagination) and the other to constructions of the physical world (creation).
