Quote by B.F. Skinner

"The consequences of behavior determine the probability that the behavior will occur again."

"Education is what survives when what has been learned has been forgotten."

"We are not going to be able to operate our spaceship Earth successfully nor make our impassioned plea for another chance unless we see it whole."

"The problem is that we are trying to maintain a technological society with a Stone Age emotion."

"Face your fears with courage."

"You can't live your life in fear."

"Snakes. Why'd it have to be snakes?"

"Fear is just another obstacle to overcome."
