 Since the principle of sufficient reason is – given Schopenhauer’s inspiration from Kant – the epistemological form of the human mind, the spatio-temporal world is the world of our own reflection. To that extent, Schopenhauer says that life is like a dream. As a condition of our knowledge, Schopenhauer believes that the laws of nature, along with the sets of objects that we experience, we ourselves create in way that is not unlike the way the constitution of our tongues invokes the taste of sugar. As Galileo Galilei (1564–1642) states in “The Assayer” (1623), if ears tongues and noses were removed from the world, then odors, tastes, and sounds would be removed as well.
