José Ortega y Gasset was a Spanish liberal philosopher and essayist working during the first half of the 20th century while Spain oscillated between monarchy, republicanism and dictatorship. He was, along with Kant, Schopenhauer, and Nietzsche, a proponent of the idea of perspectivism.
I wish there were more philosophers like Ortega. Ortega writes only good essays, never bad ones, about ten pages each, fertile with interesting thoughts, sometimes correct, sometimes incorrect, but always reflective of deep and penetrating thought. It's interesting to know that he was troubled by his failure to write a system of philosophy along the lines of Kant or Hegel. Frankly, I'm glad he didn't. The philosophical systems of the past 300 years have a strong propensity towards becoming 1000 pages of irrational drool couched in rare and obscure terminology.
