”Candelaria shows that Unamuno’s and Caso’s philosophical concerns are not exclusive of particular groups or countries; on the contrary, they are problems which occupied their contemporaries and which are not yet resolved. Their analysis and discussion is therefore still pertinent in our days … Candelaria considers that Unamuno and Caso are not really philosophers but essay-writers who philosophize as men of “flesh and bone” about philosophical issues. Candelaria is right to note and contextualize the importance of Unamuno and Caso, as well as their influence in the next generations. Their followers, even when critical of work, used their ideas to back up their alternative searches and proposals in the fields of culture and philosophy … This book is addressed to a non-specialized public since its structure and language are accessible to novices in philosophy and readers who barely know Unamuno or Caso. It thus adequately fulfils its informative objective. Its main achievement is to richly contextualize Unamuno’s and Caso’s thought with philosophical schools and canonical authors of different periods and latitudes, European and English-speaking in particular, as well as with references to Spanish American authors and currents of thought which are less known to the Anglo-speaking reader … I believe it is a useful essay for those who take an interest in knowing more about the Spanish or the Mexican.” – María Cristina Campos Fuentes (translated by Stella Villarmea), in: L’Érudit franco-espagnol, Vol. 3, Spring 2013
