This, and variants of it, have been been widely circulated as a Quaker saying since at least 1869, and attributed to Grellet since at least 1893. W. Gurney Benham in Benham's Book of Quotations, Proverbs, and Household Words (1907) states that though sometimes attributed to others, "there seems to be some authority in favor of Stephen Grellet being the author, but the passage does not appear in any of his printed works." It appears to have been published as an anonymous proverb at least as early as 1859, when it appeared in Household Words : A Weekly Journal.
It has also often become attributed to the more famous Quaker William Penn, as well as others including Mahatma Gandhi and Ralph Waldo Emerson.
Variants:
I expect to pass through this world but once. If, therefore, there be any kindness I can show, or any good thing I can do any fellow human being let me do it now. Let me not defer or neglect it, for I will not pass this way again.
Writing of an unnamed Quaker, as quoted in Scott's Monthly Magazine Vol. VII, No. 6 (June 1869, p. 475, edited by William J. Scott
I expect to pass through this world but once. Any good thing, therefore, that I can do or any kindness I can show to any fellow human being let me do it now. Let me not defer nor neglect it, for I shall not pass this way again.
As quoted anonymously in Hour by Hour; or, The Christian's Daily Life (1885), compiled by E.A.L., p. 37, and as "the old Quaker's words" in The Unitarian Vol. VI (July 1891); this version was given the title "Do It Now" in Heart Throbs: In Prose and Verse (1905) by Joe Mitchell Chapple.
I shall pass through this world but once! Any good thing, therefore, that I can do or any kindness that I can show to any human being, let me do it now, in his name, and for his sake! Let me not defer or neglect it, for I shall not pass this way again.
Anonymous quotation on a card, as quoted in The Friend, Vol. 61 (1888) by The Society of Friends, p. 364
I shall pass through this world but once. Any good, therefore, that I can do or any kindness I can show to any human being, let me do it now. Let me not defer or neglect it, for I shall not pass this way again.
Anonymous quotation on a card, as quoted in A Memorial of a True Life : A Biography of Hugh McAllister Beaver (1898) by Robert Elliott Speer, p. 169
I expect to pass through this world but once. If, therefore, there be any kindness I can show, or any good thing I can do, to any fellow being let me do it now. Let me not defer nor neglect it, for I shall not pass this way again.
As quoted anonymously in The Lamp Vol. XXVI (February-July 1903)
Disputed

“O mortals, from your fellows' blood abstain,
Nor taint your bodies with a food profane:
While corn, and pulse by Nature are bestow'd,
And planted orchards bend their willing load;
While labour'd gardens wholesom herbs produce,
And teeming vines afford their gen'rous juice;
Nor tardier fruits of cruder kind are lost,
But tam'd with fire, or mellow'd by the frost;
While kine to pails distended udders bring,
And bees their hony redolent of Spring;
While Earth not only can your needs supply,
But, lavish of her store, provides for luxury;
A guiltless feast administers with ease,
And without blood is prodigal to please.”
Parcite, mortales, dapibus temerare nefandis
corpora! sunt fruges, sunt deducentia ramos
pondere poma suo tumidaeque in vitibus uvae,
sunt herbae dulces, sunt quae mitescere flamma
mollirique queant; nec vobis lacteus umor
eripitur, nec mella thymi redolentia florem:
prodiga divitias alimentaque mitia tellus
suggerit atque epulas sine caede et sanguine praebet.

Epistles

1910s, Address to the Knights of Columbus (1915)
Context: For thirty-five years I have been more or less actively engaged in public life, in the performance of my political duties, now in a public position, now in a private position. I have fought with all the fervor I possessed for the various causes in which with all my heart I believed; and in every fight I thus made I have had with me and against me Catholics, Protestants, and Jews. There have been times when I have had to make the fight for or against some man of each creed on ground of plain public morality, unconnected with questions of public policy. There were other times when I have made such a fight for or against a given man, not on grounds of public morality, for he may have been morally a good man, but on account of his attitude on questions of public policy, of governmental principle. In both cases, I have always found myself 4 fighting beside, and fighting against, men of every creed. The one sure way to have secured the defeat of every good principle worth fighting for would have been to have permitted the fight to be changed into one along sectarian lines and inspired by the spirit of sectarian bitterness, either for the purpose of putting into public life or of keeping out of public life the believers in any given creed. Such conduct represents an assault upon Americanism. The man guilty of it is not a good American. I hold that in this country there must be complete severance of Church and State; that public moneys shall not be used for the purpose of advancing any particular creed; and therefore that the public schools shall be non-sectarian. As a necessary corollary to this, not only the pupils but the members of the teaching force and the school officials of all kinds must be treated exactly on a par, no matter what their creed; and there must be no more discrimination against Jew or Catholic or Protestant than discrimination in favor of Jew, Catholic or Protestant. Whoever makes such discrimination is an enemy of the public schools.

2013, Fifth State of the Union Address (February 2013)

<p>Les ondulations de ces montagnes infinies, que leurs couches de neige semblaient rendre écumantes, rappelaient à mon souvenir la surface d'une mer agitée. Si je me retournais vers l'ouest, l'Océan s'y développait dans sa majestueuse étendue, comme une continuation de ces sommets moutonneux. Où finissait la terre, où commençaient les flots, mon oeil le distinguait à peine.</p><p>Je me plongeais ainsi dans cette prestigieuse extase que donnent les hautes cimes, et cette fois, sans vertige, car je m'accoutumais enfin à ces sublimes contemplations. Mes regards éblouis se baignaient dans la transparente irradiation des rayons solaires, j'oubliais qui j'étais, où j'étais, pour vivre de la vie des elfes ou des sylphes, imaginaires habitants de la mythologie scandinave; je m'enivrais de la volupté des hauteurs, sans songer aux abîmes dans lesquels ma destinée allait me plonger avant peu.</p>

Mr. Muhammad teaches that as soon as we separate from the white man, we will learn that we can do without the white man just as he can do without us. The white man knows that once black men get off to themselves and learn they can do for themselves, the black man's full potential will explode and he will surpass the white man.
