Empirical evidence, also known as sense experience, is the knowledge or source of knowledge acquired by means of the senses, particularly by observation and experimentation.
We rely upon all parts of our bodies when gathering empirical evidence but we mostly rely on our brains to process the information that becomes the empirical evidence. To be more specific, we use our nervous system which is divided into central nervous system (brain, spinal cord) and the peripheral nervous system (mainly consists pf nerves) which are long fibres or axons that connect CNS to all parts of the body.
Ambiguity is a type of meaning in which several interpretations are plausible. A common aspect of ambiguity is uncertainty. It is thus an attribute of any idea or statement whose intended meaning cannot be definitively resolved according to a rule or process with a finite number of steps.The concept of ambiguity is generally contrasted with vagueness. In ambiguity, specific and distinct interpretations are permitted (although some may not be immediately obvious), whereas with information that is vague, it is difficult to form any interpretation at the desired level of specificity.
