The basic question of human existence is: does the decomposition of my terrestrial body also mean the destruction of my conscious being?Drawing upon scientific and philosophic sources Hermann de Witt seeks to prove that, since according to the laws of physics, energy is never destroyed but rather transformed, the energy of the soul similarly experiences a constant process of transformation, or reincarnation. The author presents the reader with a series of analogies comparing the human body and mind to everyday objects and practices, thus bringing this complex issue down to earth. Just as he recommends that we look within ourselves, pursuing self-knowledge and the search for our soul, so too does he strip his own philosophy down to its roots.
