Our mistake is not that we take our theories too seriously, but that we do not take them seriously enough.
Steven WeinbergIf (the antiproton) had not been discovered, the foundations of physics really would have crumbled.
Steven WeinbergThe fact that Newton and Michael Faraday and other scientists of the past were deeply religious shows that religious skepticism is not a prejudice that governed science from the beginning, but a lesson that has been learned through centuries of experience in the study of nature.
Steven WeinbergHow strange it would be if the final theory were to be discovered in our lifetimes! The discovery of the final laws of nature will mark a discontinuity in human intellectual history, the sharpest that has occurred since the beginning of modern science in the seventeenth century. Can we now imagine what that would be like?
