"Made weak by time and fate, but strong in will To strive, to seek, to find, and not to yield." These words were written by which poet?

In the poem 'Ulysses' by Lord Alfred Tennyson who lived from 1809 - 1892, we have the quote: "Made weak by time and fate, but strong in will To strive, to seek, to find, and not to yield."

This is a 19th century poem, and Tennyson is said to have written it in a somewhat archaic style. Experts and historians point out that the warrior Ulysses was addressing the men (mariners) who traveled with him. They were the men that he led to Troy, and they under went many dangers with him on the return voyage home. So in Tennyson's poem, he's saying “We aren’t that band of young warriors we once were, men capable of anything; but what we still are is heroically willing to try to do our utmost.” We may have weak bodies. But we still have strong minds.

A footnote to the quote in 'Ulysses' is that Tennyson appears to have forgotten that Ulysses returned to Ithaca alone, all his companions perished along the way.
