It is a demonstration that analysis of the qualitative side of life is possible without descending to symbolism or the vagaries of "New Thoughtism."

–R.S. Bourne, from the Journal of Philosophy, Psychology, & Scientific Methods, September 1912

If it were not for the fear of false interpretations–sentimental New-thoughtism, Kantian intentionism, or pietistic literalism, one would have avoided this enumeration by two quotations:"The Kingdom of Heaven is within you" and "As a man thinketh in his heart so he is."

–Albert K. Weinberg, from the International Journal of Ethics, July 1923
