evidential appeal
An attempt to show the logical connection between a set of evidence and a consequence. Also known as logical appeal or logos.
Logos (Evidential or Logical Appeal)
From a rationalist's point of view, evidential appeals are the only type of appeal that truly matter. Evidential appeals are formed by defining the evidence and then explaining how the evidence must logically prove that a certain conclusion must be true. Evidential appeals are the only type of persuasive speech allowed in a court of law; the evidence must prove that the defendant has committed the crime in order for that person to be found guilty .
Evidential appeals are also the basis for scientific research. A scientist must be able to show the connection between evidence and a conclusion in order for his/her work to be accepted. In persuasive speaking, the speaker must first explain the evidence in a way that is comprehensible to the audience, yet complete. Then the scientist must explain how that evidence logically leads to a consequence that supports his/her proposal.
