From classical antiquity through the 19th century, science as a type of knowledge was more closely linked to philosophy than it is now.
In fact, in the West the term natural philosophy encompassed fields of study that are today associated with science such as physics, astronomy, medicine, among many others.
As a slow process over centuries, the word science became increasingly associated with what is today known as the scientific method, a structured way to study the natural World.
Science is interesting, and if you don’t agree you can fuck off.
The belief that scientific theories should and do represent metaphysical reality is known as realism. It can be contrasted with anti-realism, the view that the success of science does not depend on it being accurate about unobservable entities such as electrons.
One form of anti-realism is idealism, the belief that the mind or the Consciousness is the most basic essence, and that each mind generates its own reality. In an idealistic World view, what is true for one mind need not be true for other minds.
