This book makes the attempt to wed reason and the poetic. The tool for this attempt is Rational Poetic Experimentalism (RPE), which is introduced and explored in this book. According to RPE, it makes sense to look for poetic elements in human reality (including reason), outside of the realm of imaginative literature. Provocatively, RPE contends that philosophy’s search for truth has not been a great success so far. So, why not experiment with philosophical concepts and look for thought-provoking ideas by employing the principles of RPE, instead of fruitlessly searching for truths using conventional methods?
