Drawn by British cartoonist John Landers based on an idea from Dennis earl. Free to use in the classroom and on course websites.
We can never achieve absolute truth but we can live hopefully by a system of calculated probabilities. The law of probability gives to natural and human sciences - to human experience as a whole - the unity of life we seek. Quote of American educator Agnes E Meyer (1887 - 1970) appearing in her book "Education for a New Morality" (MacMillan, 1957) p. 21. Also to be found in "Statistically Speaking the dictionary of quotations" compiled by Carl Gaither and Alma Cavazos-Gaither p. 131
