You can do whatever you want, but most of us don't try to operate in a system where the only knowledge that can exist is that which is verified by the scientific method. In fact, inherent to the scientific method is an underlying philosophy of science which does not come from science, nor could it without being at best circular reasoning.

Science and the scientific method is basically the best means by which we can understand the physical world, but it doesn't help us determine the nature of truth, ethics, or the nature of science. It works on various assumptions (e.g. physical matter actually exists, it is possible to gain knowledge about physical matter, there is such a thing as time, logic is a valid aapproach to determining truth) that it cannot validate.
