by accident...

But after years of experiments that actually bankrupted his family, Charles Goodyear finally realized his dream; he discovered, quite by accident, how to stabilize the sap he was so obsessed with and received his first patent for “vulcanizing” (from Vulcan, the Roman god of fire) rubber in 1837.

The narrative about a major invention follows the pattern of a fairy tale (волшебная сказка). The main character goes out into the woods and by pure accident discovers a magic object. Fuck.

upd: in Searle's terms we should not confuse a prior intention with an intention in action. 

Quote of the Day

Although estimates vary, military history experts generally agree that the average GI who served in Europe from D day to the end of the war had sex with about twenty-five women. By the time Germany surrendered, the US occupying army had to ration condoms to four per soldier per month, something an army official complained was “entirely inadequate.”
When the American military occupied Italy, it was estimated that 75 percent of all soldiers had sex regularly with Italian women.
