Brayton Polka's book, On Poetry and Philosophy: Thinking Metaphorically with Wordsworth and Kant, is unique in bringing poetry and philosophy together in a single study. The poet and the philosopher whom he makes central to his project are both revolutionary founders of modernity, Wordsworth of romantic poetry and Kant of critical philosophy. Both the poet and the philosopher, as the author makes clear in his study, found their principles, at once poetically metaphorical and philosophically critical, on the religious values that are central to the Bible—that all human beings are equal before God.
