Wittgenstein developed what has come to be known as “Ordinary-Language Philosophy” while Carl Popper wrote on science and “The Open Society and its Enemies.” Convener: Richard Dowen is Professor Emeritus in the NIU Department of Finance. He has led LLI sessions ranging from Military History to Investments. Attendance for any or all LLI programs this season is $85.00 per person.
