Thus Roger Chillingworth scrutinised his patient carefully, both as he saw him in his ordinary life, keeping an accustomed pathway in the range of thoughts familiar to him, and as he appeared when thrown amidst other moral scenery, the novelty of which might call out something new to the surface of his character.  He deemed it essential, it would seem, to know the man, before attempting to do him good.  Wherever there is a heart and an intellect, the diseases of the physical frame are tinged with the peculiarities of these.  In Arthur Dimmesdale, thought and imagination were so active, and sensibility so intense, that the bodily infirmity would be likely to have its groundwork there.  So Roger Chillingworth—­the man of skill, the kind and friendly physician—­strove to go deep into his patient’s bosom, delving among his principles, prying into his recollections, and probing everything with a cautious touch, like a treasure-seeker in a dark cavern.  Few secrets can escape an investigator, who has opportunity and licence to undertake such a quest, and skill to follow it up.  A man burdened with a secret should especially avoid the intimacy of his physician.  If the latter possess native sagacity, and a nameless something more,—­let us call it intuition; if he show no intrusive egotism, nor disagreeable prominent characteristics of his own; if he have the power, which must be born with him, to bring his mind into such affinity with his patient’s, that this last shall unawares have spoken what he imagines himself only to have thought; if such revelations be received without tumult, and acknowledged not so often by an uttered sympathy as by silence, an inarticulate breath, and here and there a word to indicate that all is understood; if to these qualifications of a confidant be joined the advantages afforded by his recognised character as a physician;—­then, at some inevitable moment, will the soul of the sufferer be dissolved, and flow forth in a dark but transparent stream, bringing all its mysteries into the daylight.

Roger Chillingworth possessed all, or most, of the attributes above enumerated.  Nevertheless, time went on; a kind of intimacy, as we have said, grew up between these two cultivated minds, which had as wide a field as the whole sphere of human thought and study to meet upon; they discussed every topic of ethics and religion, of public affairs, and private character; they talked much, on both sides, of matters that seemed personal to themselves; and yet no secret, such as the physician fancied must exist there, ever stole out of the minister’s consciousness into his companion’s ear.  The latter had his suspicions, indeed, that even the nature of Mr. Dimmesdale’s bodily disease had never fairly been revealed to him.  It was a strange reserve!
