"...I thank those that have taught me... but..."

"If in some things I dissent from others, whose wit, industry, diligence, and judgment, I look up to and admire, let me not therefore hear presently of ingratitude and rashness. For I thank those that have taught me, and will ever; but yet dare not think the scope of their labor and inquiry was to envy their posterity what they could add and find out."

-from Ben Jonson's Timber, 1640 (p. 7 of the 1892 edition, ed. Schelling).
