"For Architecture b Architecture being an Art that has scarce any other Rule to walk by in performing all those Excellencies her Works are capable of than what we call a Good Fancy which truly distinguishes that which is Beautiful and Good from that which is not so; it's absolutely necessar y that one be perswaded that the Fancy he follows is better than any other; to the end that this Perswasion insinuating it self into them that study this Art it may form in them a Correct and Regular Idea which without this Perswasion would be always floating and uncertain; so that to establish this Good Fancy it's necessar y to have one to whom we give great deference and who has merited great Credit by the Learning that is found in his Writings; and is believed to have had sufficient abilities of chusing well among all Antiquity that which is most solid and capable of founding the Precepts of Architecture."
