Spanish term (edited): tendencia idealista (neo-kantiana o neo-fitzchetiana)

I can't imagine what else this would be. Here is a reference to Kuno Fischer's influence on neo-Kantianism (http://en.wikipedia.org/wiki/Neo-Kantian):

Neo-Kantianism means a revived or modified type of philosophy along the lines of that laid down by Immanuel Kant in the eighteenth century or (sometimes) by Schopenhauer's criticism of the Kantian philosophy in his work The World as Will and Representation. It has some more specific reference in later German philosophy. The "back to Kant" movement began in the 1860s, as a reaction to the materialist controversy in German thought in the 1850s.[1]

Early fruits of the movement were Kuno Fischer's works on Kant and Friedrich Lange's History of Materialism (Geschichte des Materialismus), the latter of which demonstrated the way in which transcendental idealism superseded the historic struggle between material idealism and mechanistic materialism. Fischer was early involved in a dispute with the Aristotelian Friedrich Adolf Trendelenburg concerning the interpretation of the results of the Transcendental Aesthetic, a dispute that subsequently prompted Vaihinger's massive commentary on the Critique of Pure Reason.

My take. Good luck.

Fichte is a philosopher close chronologically to Kant.

Yes, the Spanish spelling is someone's idea of phonetic.
