fect Simplicity and Uniformity. The Case is not the same in this Species of Philosophy as in Physics. Many an Hypothesis in Nature, contrary to first Appearances, has been found, on more accurate Scrutiny, solid and satisfactory. Instances of this Kind are so frequent, that a judicious, as well as witty Philosopher[1] has ventur'd to affirm, if there be more than one Way, in which any Phænomenon may be produc'd, that there is a general Presumption for its arising from the Causes, which are the least obvious and familiar. But the Presumption always lies on the other Side, in all Enquiries concerning the Origin of our Passions, and the internal Operations of the human Mind. The simplest and most obvious Cause, that can there be assign'd for any Phænomenon, is probably the true one. When a Philosopher, in the Explication of his System, is oblig'd to have Recourse to some very intricate and refin'd Reflections, and to suppose them essential to the Production of any Passion or Emotion, we have Reason to be extremely on our Guard against so fallacious an Hypothesis. The Affections are not susceptible of any Impression from the Refinements of Reason or Imagination; and 'tis always found, that a vigorous Exertion of the latter Faculties, from the narrow Capacity of the human Mind, destroys all Energy and Activity in the former.
