[Ortega and the theory of relativity]

Ortega y Gasset's thinking on Einstein and relativity, set out in the course of his extensive works, is constructed in the light of three of his fundamental ideas: 1) science, a special form of belief; 2) physics, a science par excellence; and 3) relativity, the intellectual fact of the highest order of its time; dedicating special attention to the essay: "The historical meaning of Einstein's theory". And it is completed with his critical attitude to the so-called "fundamental crisis" and his diagnosis of the grave problems suffered by physics in the wake of the relativistic and quantum revolutions.
