Book excerpt: The modernist poetry of Wallace Stevens is replete with moments of theorizing. Stevens regarded poetry as an abstract medium through which to think about and theorize not only philosophical concepts like metaphor and reality, but also a unifying thesis about the nature of poetry itself. At the same time, literary theorists and philosophers have often turned to Stevens as a canonical reference point and influence. In the centenary year of Wallace Stevens's first collection Harmonium (1923), this collection asks what it means to theorize with Stevens today. Through a range of critical and theoretical perspectives, this book seeks to describe the myriad kinds of thinking sponsored by Stevens's poetry and explores how contemporary literary theory might be invigorated through readings of Stevens.
