I doubt therefore I am

Evidence is now used more to cast doubt then to represent truth. As a culture we accept that some data could be interpreted in a way that cast some sliver of doubt, no matter how slight, on an accepted truth. Some how doubt is accepted as proof that truth does not exist. This is only possible if we do not look at the evidence in context. Context is everything. A bloody knife suggests foul play. The knife has no context, but it is bloody so... A bloody knife on a cutting board next to a steak that has been trimmed is another thing entirely. Evidence is not in a vacuum. Doubt is not proof even if it is a reasonable doubt.
