Philosophy Simplex: The Artist of Energy by Alexander Leonhard This book is a compact journey through the foundations of philosophy, written with clarity, wonder, and originality. Across six chapters, Alexander Leonhard explores imagination, perception, knowledge, freedom, civilization, and existence itself — weaving poetry and reasoning into a new vision of the world. Principles of Imagination reveals creativity not as mystery, but as method — powered by addition, variation, and transformation. - The Blue Sky finds wonder in the ordinary, showing how clouds never repeat yet the sky endures. - Are Numbers Invented or Discovered? reflects on zero, infinity, and the rise of calculus, offering a fresh account of how concepts and systems emerge. - Free Will reframes freedom as a phase — expanding and contracting with time, tools, and imagination — and introduces the idea of collective will. - Planetary Philosophy asks what responsibility humanity carries for Earth and beyond, measuring civilizations not by permanence but by contribution. - Interactions and Properties offers a bold new ontology: existence arises from interaction, properties cohere into higher realities, and God transcends even existence itself. Philosophy Simplex is not academic philosophy, but philosophy in motion — accessible, poetic, and alive. It challenges readers to see reality as puzzle, paradox, and transcendence, and to live with both responsibility and wonder.
