Philosophy, it's not essentially about curiosity.

[I]t has long been known that the Greeks recognized thaumazein as the “beginning” of philosophy. But it is just as certain that we have taken this thaumazein to be obvious and ordinary, something that can be accomplished without difficulty and can even be clarified without further reflection. For the most part, the usual presentations of the origin of philosophy out of thaumazein result in the opinion that philosophy arises from curiosity. This is a weak and pitiful determination of origin, possible only where there has never been any reflection on what is supposed to be determined here in its origin. Indeed, we consider ourselves relieved of such reflection, precisely because we think that the derivation of philosophy out of curiosity also determines its essence.
