Cause to Effect
Just as the explainer may pass from cause to effect so may the arguer. Other names for this method are antecedent probability and a priori argument. In argument from a known cause an effect is proven as having occurred or as likely to occur. In solving crime this is the method which uses the value of the motives for crime as known to exist in the feelings or sentiments of a certain accused person.
A person trying to secure the passage of a certain law will prove that it as the cause will produce certain effects which make it desirable. Changed conditions in the United States will be brought forward as the cause to prove that the Federal government must do things never contemplated by the framers of the Constitution. Great military organization as the cause of the recent war is used now in argument to carry on the plea for the securing of peace by disarmament.
The main difficulty in reasoning from cause to effect is to make the relationship so clear and so close that one thing will be accepted by everybody as the undisputed cause of the alleged effect.
