Identifying Author's Tone

In a thought-provoking essay discussing the role of art in society, the author writes:

"Art exists not merely to entertain but to provoke thought, to challenge the mundane perceptions we hold about our world. In a society often driven by utilitarian values, the nuances of creativity can appear frivolous. Yet, it is precisely through the lens of the artistic that we come to grapple with profound truths that we might otherwise avoid. Consider the way a single painting can evoke emotions that stir the very core of our humanity, or how a haunting melody can transport us to memories long forgotten. Art reminds us that while logic and reason have their place, the realm of human experience is undeniably richer and more complex when viewed through the myriad colors of expression."
