Curiosity is, and has been from the creation of the world, a master-passion. To awaken it, to gratify it by slight degrees, and yet leave something always in suspense, is to establish the surest hold that can be had, in wrong, on the unthinking portion of mankind.
~ Barnaby Rudge
by Charles Dickens
"You might have married him not because you loved him, but because you didn't love anybody else. When one is young, one marries out of mere curiosity, just to see what it's like."
~ The Philanderer
by George Bernard Shaw
The human brain is capable of only one strong emotion at a time, and if it be filled with curiosity or scientific enthusiasm, there is no room for fear.
~ The Brown Hand
by Sir Arthur Conan Doyle
