On January 4, 2016, the B. F. Skinner Foundation launched a new project – Skinner’s Quote of the Day. Quotes from B. F. Skinner’s works, selected by renowned scientists, appear daily Monday-Friday in order, starting with Chapter 1 of each book and running all the way through the last chapter. We started with the Science and Human Behavior (January-December 2916), followed by About Behaviorism (January-November 2017), Contingencies of Reinforcement (January-October 2018), Recent Issues (October 2018-May 2019), Reflections on Behaviorism and Society (May 2019-February 2020), and now moving on to Upon Further Reflection (from February 10 2020).
