The proposition that the only way to knowledge is by science or that science constitutes the only valid knowledge is a belief that itself is not derived from science, it is a philosophical statement about science, so it is self-refuting. I presume you mean testable in some scientific, or experimental sense, which excludes a lot of evidence at the outset.

"The proposition that the only way to knowledge is by science or that science constitutes the only valid knowledge is a belief that itself is not derived from science, it is a philosophical statement about science, so it is self-refuting."

Luckily I never said that science is the only way to knowledge or that science constitutes the only valid knowledge.

"I presume you mean testable in some scientific, or experimental sense, which excludes a lot of evidence at the outset."

What evidence?
