“We can pay our debts to the past by putting the future in debt to ourselves.”

1870s, Society and Solitude (1870), Quotation and Originality
Context: We cannot overstate our debt to the Past, but the moment has the supreme claim. The Past is for us; but the sole terms on which it can become ours are its subordination to the Present. Only an inventor knows how to borrow, and every man is or should be an inventor. We must not tamper with the organic motion of the soul.

We Wear The Mask, in the 1913 collection of his work, The Complete Poems of Paul Laurence Dunbar.
Context: We wear the mask that grins and lies,
It hides our cheeks and shades our eyes,—
This debt we pay to human guile;
With torn and bleeding hearts we smile,
And mouth with myriad subtleties.

Why should the world be over-wise,
In counting all our tears and sighs?
Nay, let them only see us, while
We wear the mask.

We smile, but, O great Christ, our cries
To thee from tortured souls arise.
We sing, but oh the clay is vile
Beneath our feet, and long the mile;
But let the world dream otherwise,
We wear the mask!

Context: If archeology had yielded only the Epic of Kret, we would have enough to bridge the gap between the Iliad and Genesis. But... our new sources are so rich that we have only begun...

Our debt to the Bible and Classics is so great that this type of research will deepen our understanding of our culture and of ourselves.
