In answer to this Demand I consider, that as Light is always visible to us if we have an Organ to receive it, if we turn our Eyes towards it, and that nothing interpose between it and us; so is Truth, we are surrounded with it, and GOD has given us Faculties to receive it. If it be ask’d, Why then do we so seldom find it? The Reason is, because instead of making right use of our Faculties we employ them in keeping it out; we either shut our Eyes, or if we vouchsafe to open them, we are sure to view it thro such unsuitable Mediums as fail not to misrepresent it to us. As for those few Noble Spirits, who open the Windows of their Souls to let in Truth, and take the Films of Interest, Passion and Prejudice from before their Eyes, they will certainly be Enlighten’d, and cannot miss of obtaining as much Truth as they are capable of Receiving. For, to go on with the Comparison, as we can See no farther than our own Horizon, tho the Light shine never so bright around us; and as we cannot discern every Object even within that Compass Clearly, nor Any Distinctly but what we particularly apply our selves to; So neither are our Capacities large enough to take in _All_ Truth, as has been often said, nor are we capable of attaining _Any_, without Attention and diligent Examination. But if we carefully Consider those Ideas we already have and Attend to those Truths we are acquainted with, we cannot want Mediums to discover more, if our Enquiries be after that which is within our Reach. He who is the Fountain of Truth is also a GOD of Order, and has so regularly connex’d one Truth with another, that the discovery of one is a step towards a further Progress; so that if we diligently Examine those Truths which, we Know, they will clear the way to what we search after: For it seldom happens but that the Question it self directs us to some Idea that will serve for the Explanation or Proof of it.
