From among the Quaker exponents of the freedom of all men, we can scarcely select one of greater influence than John Woolman. He was born in 1720,[1159] and thus grew up to manhood in a period when the opposition to slavery on the part of Friends was on the increase, and lived through its zenith, after which slavery among Pennsylvania Friends scarcely existed.[1160] He was well educated. The greater part of his life was spent travelling as a minister from place to place, now working among the Indians[1161] and again visiting meetings in the interest of the freedom of the Negro.[1162] His journeys throughout the colonies served to keep the individual meetings awake to the problem before them, and the firm conviction of the man won no less number of supporters than the eloquence of his appeal. The influence of Woolman did not, however, limit itself to the channels of his sermons; in 1754 appeared one of his best expressions on the traffic, entitled _Some Considerations on the Keeping of Negroes_. Nothing was permitted to stand in the light of his conviction as to the right; he refused to continue his practice of writing wills in all cases where the disposition of slaves was involved.[1163] But it is impossible to give in this limited space an adequate resumé of the work of this great spokesman of freedom. A brief representative statement from his works, added to what has already been said, is perhaps the most satisfactory treatment that can be given. [Sidenote: Woolman on slave holding] Many slaves on this continent are oppressed, and their cries have reached the ears of the most High. Such are the purity and certainty of His judgments, that He can not be partial in our favor. In infinite love and goodness He hath opened our understandings from one time to another concerning our duty to this people; and it is not a time for delay. Should we now be sensible of what He requires of us, and through respect to the interest of some persons, or through a regard to some friendships which do not stand on an immutable foundation, neglect to do our duty in firmness and constancy, still waiting for some extraordinary means to bring about their deliverance, it may be by terrible things in righteousness, God may answer us in this matter.[1164] Man is born to labor, and experience abundantly sheweth that it is for our good; but where the powerful lay the burden on the inferior, without affording a Christian education, and suitable opportunity for improving the mind, and a treatment that we in their case should approve, that themselves may live at ease and fare sumptuously, and lay up riches for their posterity, this seems to contradict the design of Providence and, I doubt not, is sometimes the effect of a perverted mind; for while the life of one is made grievous by the rigor of another, it entails misery to both.[1165]
