The prevailing worldview of Western culture came into being about 600 years ago and is known as the General Scientific Model.
Every event has a cause.
Causes can be known. Humans can discover the causes of events. Ignorance of causes is due to factors such as improper tools or techniques for investigation, insufficient preparation, insufficient knowledge, insufficient time to conduct the experimental and nonexperimental tests, or insufficient support to conduct these tests. Driven by these assumptions, science holds out the lure of absolute knowledge of the universe as theoretically achievable. Practical considerations may, in fact, interfere with the attainment of this absolute knowledge, but that is a human limitation, not a limitation of the scientific method itself.
