| The Study of Evidence pays great attention to the proof of facts, while "fact" is rich in meaning. Evidence can be in abstract forms or concrete forms, and we can only make competence requirements on concrete evidence. The necessity of proof comes from the unclear relationship between "other things" and the facts to be proved. Affected by the sources of evidence and approaches of proof , the proof of facts is to a certain degree uncertain. Because the removal of uncertainty is in direct proportion to the consumption of proof resources, we should distinguish "strict proof" and "free proof" in practice. Proof and falsification are both ways of proof. Presumption and the mechanism of burden of proof are used to handle the uncertain state. The basic approaches of proof include empirical approaches, logic or non-logic approaches and relative approaches to evaluate evidences and to interpret. To establish a "General Study of Evidence"，which is based on the study of evidence in various departments of law，would help deepen the study of evidence in various departments of law. |
