As different from the tendency of driving the series of philosophical questions to the ultimate unquestionable fundaments or reasons, art supposes to restrain from such ultimate answers for the very act of being adequately approached.
To question the use of art means a wrong way of dealing with it. And to search for final answers concerning its use is a way that leads straight to its negation, being impossibly to finally detach it from a simple and useless leisure, when it is questioned about its place in the whole of the human existence.
However, art’s freedom from ultimate questions does not impede it to raise questions about those human features that it alludes at, since all that man figures out he knows unquestionably could be doubted by its appearance in a work of art. Almost like in Plato’s dialogue, our certainty that we know, for instance, what things are beautiful is doubted by the beauty of a work of art. The esthetical emotions can be interpreted as those states of puzzlement Socrates induced to his interlocutors.
Any attempt to explain art by appealing to some primary cultural or esthetical values fails to comprehend its implicit questioning. There is preferable to admit its undefinable power of addressing human existence, instead of framing it in a net of categories or values.
Likely, a philosophical discourse should be stronger if it comes out of the chains of questions purported to discover ultimate reasons. The power of philosophical ideas or questions to dissipate the large amount of certainties certificates them as being parts of a truthful philosophical account.
