What is the concept of idealism?

Idealism is a philosophical theory that emphasizes the primacy of ideas, consciousness, or the mind in understanding reality. It posits that reality is fundamentally shaped by mental constructs, perceptions, or spiritual values rather than material conditions. In contrast to materialism, which focuses on the physical world, idealism suggests that the nature of reality is inherently linked to our thoughts, beliefs, and ideals. This perspective is often associated with philosophers like Plato and George Berkeley, who argue that the material world is less significant than the realm of ideas.
