案情：2005年6月6日，甲、乙、丙三兄弟的父亲死亡，留了一份遗嘱，将其生前收藏的—。幅名画留给了这三兄弟。并指定由老大甲负责保管。同年9月，甲遇丁，丁愿购此画。甲即将此画作价3万元卖给丁。事后，甲告知乙、丙。乙、丙要求分得卖画款项，甲分别给乙、丙各1万元。
丁购买该画后，于同年12月又将此画以4万元卖给戊。两人约定：合同签订后，即将画交付戊，但因丁将在半年内举办个人收藏品展，故自该画交付之日起半年后画的所有权才将转移于戊。依此约定，丁将画交付戊，戊先期支付价款3万元。2006年3月，戊因生意失败向其朋友己借款5万元，戊友己亦爱此画，便要求戊质押该画作为借款的担保，戊与己签订了质押合同，并将画交给了己。后己嫌该画的装裱不够精美，遂将该画送庚装裱店装裱。因己未按期付庚装裱店费用，该画被庚装裱店留置。庚装裱店通知己应在30日内向其支费用，但己仍未能按期支付。庚装裱店遂将画折价受偿，扣除费用，将差额补偿给己。己不同意庚装裱店的这一做法。

The most thoroughly studied intellectuals in the history of the New World are the ministers and political leaders of seventeenth-century New England. According to the standard history of American philosophy, nowhere else in colonial America was “so much importance attached to intellectual pursuits.” According to many books and articles, New England’s leaders established the basic themes and preoccupations of an unfolding, dominant Puritan tradition in American intellectual life.

To take this approach to the New Englanders normally means to start with the Puritans’ theological innovations and their distinctive ideas about the church—important subjects that we may not neglect. But in keeping with our examination of southern intellectual life, we may consider the original Puritans as carriers of European culture, adjusting to New World circumstances. The New England colonies were the scenes of important episodes in the pursuit of widely understood ideals of civility and virtuosity.

The early settlers of Massachusetts Bay included men of impressive education and influence in England. Besides the ninety or so learned ministers who came to Massachusetts churches in the decade after 1629, there were political leaders like John Winthrop, an educated gentleman, lawyer, and official of the Crown before he journeyed to Boston. These men wrote and published extensively, reaching both New World and Old World audiences, and giving New England an atmosphere of intellectual earnestness.

We should not forget, however, that most New Englanders were less well educated. While few crafts men or farmers, let alone dependents and servants, left literary compositions to be analyzed, it is obvious that their views were less fully intellectualized. Their thinking often had a traditional superstitious quality. A tailor named John Dane, who emigrated in the late 1630s, left an account of his reasons for leaving England that is filled with signs. Sexual confusion, economic frustrations, and religious hope—all came together in a decisive moment when he opened the Bible, told bas father that the first line he saw would settle his fate, and read the magical words: "Come out from among them, touch no unclean thing, and I will be your God and you shall be my people." One wonders what Dane thought of the careful sermons explaining the Bible that he heard in Puritan churches.

Meanwhile, many settlers had slighter religious commitments than Dane’s, as one clergyman learned in confronting folk along the coast who mocked that they had not come to the New World fur religion. "Our main end was to catch fish.
