Evidence in Problems
The theory of evidence is a field wrought with dispute. Many of these disputes stem from the limits of human knowledge, a field known as epistemology. Possibly the most salient question of evidence is how, if, and what, one can know. (Or, in other words, the question is to what extent is it even possible to fulfill the burden of proof.) This is the question of evidence's limits. Some believe all evidence to be circumstantial, denying the possibility of direct evidence.
To help deal with this problem, many fields have found it useful to talk about levels of evidence and certainty, particularly the field of law.

Famous quotes containing the words evidence and/or problems:
“Generally there is no consistent evidence of significant differences in school achievement between children of working and nonworking mothers, but differences that do appear are often related to maternal satisfaction with her chosen role, and the quality of substitute care.”
—Ruth E. Zambrana, U.S. researcher, M. Hurst, and R.L. Hite. “The Working Mother in Contemporary Perspectives: A Review of Literature,” Pediatrics (December 1979)
“While the onset of puberty can vary by as much as six years, every adolescent wants to be right on the 50-yard line, right in the middle of the field. One is always too tall, too short, too thin, too fat, too hairy, too clear-skinned, too early, too late. Understandably, problems of self-image are rampant.”
—Joan Lipsitz (20th century)
