Famous quotes containing the words common and/or designs:
“So didst thou travel on lifes common way,
In cheerful godliness; and yet thy heart
The lowliest duties on herself did lay.”
—William Wordsworth (17701850)
“I have no scheme about it,no designs on men at all; and, if I had, my mode would be to tempt them with the fruit, and not with the manure. To what end do I lead a simple life at all, pray? That I may teach others to simplify their lives?and so all our lives be simplified merely, like an algebraic formula? Or not, rather, that I may make use of the ground I have cleared, to live more worthily and profitably?”
—Henry David Thoreau (18171862)
