What belief posits that no world exists apart from mind-dependent ideas?

The belief that no world exists apart from mind-dependent ideas is known as idealism. This philosophical viewpoint asserts that reality is fundamentally constructed by the mind and its perceptions. In idealism, the external world is understood to be a product of mental processes, emphasizing the role of consciousness in shaping one's experience of reality. This perspective stands in contrast to realism, which posits that the world exists independently of our perceptions or beliefs about it, and suggests that there are objective truths and entities that exist outside of our mental experiences. Understanding idealism is crucial for philosophical discussions about the nature of reality and consciousness, especially in fields like psychology, where the interpretation of human experiences is central.
