Quote by Oliver Wendell Jr. Holmes (1841-1935)

• The ultimate good desired is better reached by free trade in ideas [and] the best test of truth is the power of the thought to get itself accepted in the competition of the market.

• Man's mind stretched to a new idea never goes back to its original dimensions.

• Sin has many tools, but a lie is the handle which fits them all.

• I find the great thing in this world is not so much where we stand, as in what direction we are moving -- we must sail sometimes with the wind and sometimes against it -- but we must sail, and not drift, nor lie at anchor.

• It is the province of knowledge to speak
  And it is the privilege of wisdom to listen.

• We should be eternally vigilant against attempts to check the expression of opinions that we loathe.
