Hester believes that her own sin and suffering have given her insights into the secrets concealed in other hearts.

Her imagination was somewhat affected, and, had she been of a softer moral and intellectual fibre, would have been still more so, by the strange and solitary anguish of her life. Walking to and fro, with those lonely footsteps, in the little world with which she was outwardly connected, it now and then appeared to Hester,--if altogether fancy, it was nevertheless too potent to be resisted,--she felt or fancied, then, that the scarlet letter had endowed her with a new sense. She shuddered to believe, yet could not help believing, that it gave her a sympathetic knowledge of the hidden sin in other hearts. She was terror-stricken by the revelations that were thus made. What were they? Could they be other than the insidious whispers of the bad angel, who would fain have persuaded the struggling woman, as yet only half his victim, that the outward guise of purity was but a lie, and that, if truth were everywhere to be shown, a scarlet letter would blaze forth on many a bosom besides Hester Prynne's? Or, must she receive those intimations--so obscure, yet so distinct--as truth? In all her miserable experience, there was nothing else so awful and so loathsome as this sense. It perplexed, as well as shocked her, by the irreverent inopportuneness of the occasions that brought it into vivid action. Sometimes, the red infamy upon her breast would give a sympathetic throb, as she passed near a venerable minister or magistrate, the model of piety and justice, to whom that age of antique reverence looked up, as to a mortal man in fellowship with angels. "What evil thing is at hand?" would Hester say to herself. Lifting her reluctant eyes, there would be nothing human within the scope of view, save the form of this earthly saint! Again, a mystic sisterhood would contumaciously assert itself, as she met the sanctified frown of some matron, who, according to the rumor of all tongues, had kept cold snow within her bosom throughout life. That unsunned snow in the matron's bosom, and the burning shame on Hester Prynne's,--what had the two in common? Or, once more, the electric thrill would give her warning,--"Behold, Hester, here is a companion!"--and, looking up, she would detect the eyes of a young maiden glancing at the scarlet letter, shyly and aside, and quickly averted, with a faint, chill crimson in her cheeks; as if her purity were somewhat sullied by that momentary glance. O Fiend, whose talisman was that fatal symbol, wouldst thou leave nothing, whether in youth or age, for this poor sinner to revere?--Such loss of faith is ever one of the saddest results of sin. Be it accepted as a proof that all was not corrupt in this poor victim of her own frailty, and man's hard law, that Hester Prynne yet struggled to believe that no fellow-mortal was guilty like herself.
