Science has provided the swiftest communicationbetween individuals; it has provided a record of ideas andhas enabled man to manipulate and to make extracts fromthat record so that knowledge evolves and endures through-out the life of a race rather than that of an individual
I believe especially the evolution of technology and new devices made this transition and provision of "the swiftest communication between individuals" possible. For the advancement of knowledge, the sharing and transferring of knowledge is the most important, so this transition was extremely important.
