The concept of play, developed by the philosopher Hans-Georg Gadamer (1900 – 2002), constitutes an attempt to consider knowledge from basis different than those established by modern sciences stemming in kantian theory. The conception of knowledge thus developed by Gadamer, originates in Martin Heidegger s hermeneutics of facticity, which he proposed in the first quarter of the XXth century, and recovers the fundamental experience of art as the primary fact of existence. Play, the centre of Gadamer s philosophical hermeneutics unveils the aporia and limitations which come as a result of treating knowledge and artistic production/appreciation as differential standards. In reconsidering the tradition of scientific and aesthetic thinking, Gadamer explores new parameters to think truth within science and art, which no longer concentrate on methodological criteria. Play, posited as the structure of understanding, allows us to see how once the tight relationship between truth and method is undone, humanities are best suited with an ontological conception of understanding, so as to approach their object more accurately.
