“Although this may seem a paradox, all exact science is dominated by the idea of approximation. When a man tells you that he knows the exact truth about anything, you are safe in inferring that he is an inexact man. Every careful measurement in science is always given with the probable error… every observer admits that he is likely wrong, and knows about how much wrong he is likely to be.”
(Bertrand Russell, 1931. The Scientific Outlook. London: George Allen & Unwin)
Bertrand Russell (1872 – 1970), Welsh mathematician, logician and philosopher known for his work in mathematical logic, but was also active in social and political campaigns, advocating pacifism and nuclear disarmament.
