On April 8, 1859, German philosopher and mathematician Edmund Gustav Albrecht Husserl was born. He is best know as the founder of the 20th century philosophical school of phenomenology, where he broke with the positivist orientation of the science and philosophy of his day, yet he elaborated critiques of historicism and of psychologism in logic.
106 years ago today, Kurt Gödel was born, one of the most significant logicians of all time. Gödel made an immense impact upon scientific and philosophical thinking in the 20th century, a time when many, such as Bertrand Russell, A. N. Whitehead and David Hilbert, were pioneering the use of logic and set theory to understand the foundations of mathematics.
