“Concern for the symbol has completely disappeared from our science.”
Simone Weil book The Need for Roots
The Need for Roots (1949), p. 292
Context: Concern for the symbol has completely disappeared from our science. And yet, if one were to give oneself the trouble, one could easily find, in certain parts at least of contemporary mathematics... symbols as clear, as beautiful, and as full of spiritual meaning as that of the circle and mediation. From modern thought to ancient wisdom the path would be short and direct, if one cared to take it.
