This text examines the origins of reflective consciousness in the thought of Pre-Socratic philosophers Xenophanes and Alcmaeon. Xenophanes is credited with distinguishing between mere lucky opinion and genuine knowledge. He argued that even a true statement remains mere appearance if the speaker lacks the awareness and ability to verify its correctness. This requirement to "know that one knows" establishes the roots of philosophical reflection and identifies it as a divine attribute, making philosophy a divine mission. Alcmaeon of Croton further developed this by differentiating human understanding from simple animal perception. He posited that senses alone are insufficient for knowledge; true understanding requires interpreting sensory data and being conscious of the act of comprehension itself. Both thinkers suggest that genuine understanding involves a duality of focus: grasping the object while simultaneously reflecting on the process of understanding. Consequently, reflection is presented as a fundamental component of human cognition, distinguishing it from mere sensory reaction.
