If Bob Dylan’s right, “the times they are changing”. But what is time anyway? We usually carve up time in terms of the past, the present and the future. But are all of these temporal divisions on an equal ontological footing? Or is there something ontologically special about the present moment, the now? If so, how should we conceive of the past and the future? Are they real? Does time really flow (like we think it does)? And what’s the relationship between space and time? Are the laws of physics time reversible? Is time travel possible? 

Philosophers have always been interested in art and aesthetic value. But what is art anyway? How should we define the notion of art? And what is it that distinguishes art from non-art? How about aesthetic value… Is aesthetic value something that resides in the object itself? Or does it have more to do with a kind of feeling, judgment, or sense of satisfaction had by an observer? Do the intentions of the artist play a role here? Should art have a purpose, such as evoking pleasure or conveying truth?
