Reading Passage: Scientists have long debated the nature of consciousness. While some argue that it is a purely biological phenomenon resulting from neural activities, others suggest that consciousness could be a fundamental aspect of the universe, akin to space and time. Recent studies have indicated that the brain operates on complex networks that allow for varying levels of consciousness, from wakefulness to deep sleep.
Furthermore, the implications of these theories extend beyond the realms of neuroscience and philosophy, as they challenge our understanding of identity and self. If consciousness is not merely a byproduct of brain function, but rather an intrinsic aspect of existence, this poses profound questions about free will and moral responsibility.
