Insoluble problems in all their insolubility...‏

'The proper method of philosophy

consists in clearly conceiving 

the insoluble problems in all their insolubility 

and then in simply contemplating them,

fixedly and tirelessly, year after year, 

without any hope, patiently waiting.   

                                         Simone Weil

Quoted by Jeremy Butterfield,

from Trinity College, Cambridge University

in a talk given in Paris, on February 2014,

entitled:

The Role of Mathematics in the Foundations of Physics
