Famous quotes containing the words matter and/or organic:
“Competition is. In every business, no matter how small or how large, someone is just around the corner forever trying to steal your ideas and build his success out of your imagination, struggling after that which you have toiled endless years to secure, striving to outdo you in each and every way. If such a competitor would work as hard to originate as he does to copy, he would much more quickly gain success.”
—Alice Foote MacDougall (1867–1945)
“And what if all of animated nature
Be but organic Harps diversely framed,
That tremble into thought, as o’er them sweeps
Plastic and vast, one intellectual breeze,
At once the Soul of each, and God of all?”
—Samuel Taylor Coleridge (1772–1834)
