Simone Weil was a French everything - critic, sociologist, activist, mystic, philosopher. She possessed a strong & committed interior life, which comes through in her fantastic writings on subjects such as attention.
Any form of true education, Weil writes, should take as its subject the amplification and purification of attention:
“Prayer being only attention in its pure form and studies being a form of gymnastics of the attention, each school exercise should be a refraction of spiritual life, There must be a method in it. A certain way of doing a Latin prose, a certain way of tackling a problem in geometry (and not just any way) make up a system of gymnastics of the attention calculated to give it a greater aptitude for prayer.”
