the danger of the sin, than he did before. And thus having done with the several reasons why man, the only creature in the world that can reflect and look into himself, is so very ignorant of what passes within him, and so much unacquainted with the standing dispositions and complexions of his own heart: I proceed now, in the _Third_ and _Last_ place, to lay down several advantages, that do _most assuredly_ attend a due improvement in the knowledge of ourselves. And, _First_: One great advantage is, that it tends very much to mortify and humble a man into a modest and low opinion of himself. For let a man take a nice and curious inspection into all the several regions of the heart, and observe every thing irregular and amiss within him: for instance, how narrow and short-sighted a thing is the understanding; upon how little reason do we take up an opinion, and upon how much less sometimes do we lay it down again, how weak and false ground do we often walk upon with the biggest confidence and assurance, and how tremulous and doubtful are we very often where no doubt is to be made. Again; how wild and impertinent, how busy and incoherent a thing is the imagination, even in the best and wisest men; insomuch that every man may be said to be mad, but every man does not shew it. Then as to the passions; how noisy, how turbulent, and how tumultuous are they, how easy they are stirred and set a-going, how eager and hot in the pursuit, and what strange disorder and confusion do they throw a man into; so that he can neither think, nor speak, nor act as he should do, while he is under the dominion of any one of them. Thus let every man look with a severe and impartial eye into all the distinct regions of the heart, and no doubt, several deformities and irregularities, that he never thought of, will open and disclose themselves upon so near a view; and rather make the man ashamed of himself, than proud. _Secondly:_ A due improvement in the knowledge of ourselves does certainly secure us from the sly and insinuating assaults of flattery. There is not in the world a baser and more hateful thing than flattery; it proceeds from so much falseness and insincerity in the man that gives it, and often discovers so much weakness and folly in the man that takes it, that it is hard to tell which of the two is most to be blamed. Every man of common sense can demonstrate in speculation, and may be fully convinced, that all the praises and commendations of the whole world can add no more to the real and intrinsic value of a man, than they can add to his stature. And yet, for all this, men of the best sense and piety, when they come down to the practice, cannot forbear thinking much better of themselves, when they have the good fortune to be spoken well of by other persons.
