摘　　要：对于演绎推理能否获取新的知识,在逻辑界意见不一致。大多数学者认为演绎推理不可获取新的知识,原因在于演绎推理的前提已经蕴涵其结论。但是从辨证发展的角度来看,演绎推理的前提未必体现出其结论,即结论相对于前提而言可以是新的知识。There are some mixed reports on whether we can obtain new knowledge from deductive reasoning. Most scholars believe that people can not obtain new knowledge from deductive reasoning because the premiss of the deductive reasoning already contains its conclusion. But from the dialectical development point of view, the premiss of deductive reasoning does not necessarily embody its conclusion, namely, the conclusion can be new knowledge relative to its premiss.
