Conjecture, assumption; something that is supposed; an opinion based on incomplete evidence.
Another and far more important reason than the delivery of a pair of embroidered gloves impelled Hester, at this time, to seek an interview with a personage of so much power and activity in the affairs of the settlement. It had reached her ears, that there was a design on the part of some of the leading inhabitants, cherishing the more rigid order of principles in religion and government, to deprive her of her child. On the supposition that Pearl, as already hinted, was of demon origin, these good people not unreasonably argued that a Christian interest in the mother’s soul required them to remove such a stumbling-block from her path. If the child, on the other hand, were really capable of moral and religious growth, and possessed the elements of ultimate salvation, then, surely, it would enjoy all the fairer prospect of these advantages by being transferred to wiser and better guardianship than Hester Prynne’s.
