A historically influential paperfolder from childhood to his last, difficult days, in several works Unamuno ironically expressed philosophical views of Platonism, scholasticism, positivism, and the "science vs religion" issue in terms of "origami" figures, notably the traditional Spanish "pajarita". Since he was also a linguist (professor of Greek), he coined the word "cocotología" ("cocotology") to describe the art of paper folding. After the conclusion of "Amor y pedagogía" ("Love and Pedagogy", 1902), he included in the volume, attributing it to one of the characters, "Notes for a Treatise on Cocotology" ("Apuntes para un tratado de cocotología").
