Abstract
Following a common assumption, when one inquires into a question, one has an inquisitive attitude towards it. More precisely, I shall assume that there is an inquisitive attitude towards Q that all of those who inquire into Q have in common and in virtue of which they can be said to be in an inquisitive state of mind towards Q. This paper is about the nature of this attitude. I elucidate it by examining whether it boils down to doubt, curiosity, epistemic desire, or wondering. I shall do this by examining whether having these attitudes is necessary and sufficient for being in an inquisitive state of mind. The test will prove negative for the first three, but the case of wondering is more complex.
