 A direct refutation may, however, be given as follows. In the above procedure the rule of inference is made a premiss and a particular inference is represented as deduced from it. But, as we have seen, that its an inversion of the true order of thought. The validity of the general rule of inference can only be apprehended in a particular inference. If we could not see the truth directly in the particular inference, we should never get the general rule at all. Thus it is impossible to deduce the particular inference from the general rule.
