The quote is from Tennyson's "Ulysses," among my favorite poems; and the source for my Google Plus tagline:
"...To follow knowledge, like a sinking star,I'm not "an idle king," and take my family obligations seriously, so I won't be setting off on a voyage of discovery. Thanks to a pretty good Internet connection and research skills, I can "follow knowledge" without leaving my desk.
"Beyond the utmost bound of human thought...."
("Ulysses," Tennyson (1833))
