Secondly, Because of obscure and imperfect Ideas.
      §10. Secondly, Our Reason is often puzled, and at a loss, because of
the obscurity, Confusion, or Imperfection of the Ideas it is employed about;
and there we are involved in Difficulties and Contradictions. Thus,
not having any perfect Idea of the least Extension of Matter, nor of
Infinity, we are at a loss about the Divisibility of Matter; but having
perfect, clear, and distinct Ideas of Number, our Reason meets with
none of those inextricable Difficulties in Numbers, nor finds it self
involved in any Contradictions about them. Thus, we having but
imperfect Ideas of the Operations of our Minds, and of the Beginning
of Motion or Thought how the Mind produces either of them in us,
and much imperfecter yet, of the Operation of GOD, run into great
Difficulties about free created Agents, which Reason cannot well
extricate it self out of.
