The Argument. Man has no notion of moral fitness but from Education. Naturally he is only a natural organ subject to Sense.

I. Man cannot naturally Perceive but through his natural or bodily organs.
II. Man by his reasoning power can only compare & judge of what he has already perciev'd.
III. From a perception of only 3 senses or 3 elements none could deduce a fourth or fifth.
IV. None could have other than natural or organic thoughts if he had none but organic perceptions.
V. Man's desires are limited by his perceptions; none can desire what he has not perceiv'd.
VI. The desires & perceptions of man, untaught by any thing but organs of sense, must be limited to objects of sense.

Conclusion. If it were not for the Poetic or Prophetic character the Philosophic & Experimental would soon be at the ratio of all things, & stand still unable to do other than repeat the same dull round over again.
