"Every hour is saved from that eternal silence"-bring out the meaning of the line from Tennyson's "Ulysses".

Ulysses really doesn't want to stay in Ithaca wasting away as an old man. His phrase "but every hour is saved / From that eternal silence, something more, / A bringer of new things" is strange. It means something like "each additional hour that I live, or each hour that I am saved from death, brings me new experiences." He wants to make those experiences count for something special.
