An idealist is someone who believes in the power of ideas and dreams to shape a better world. They often focus on what could be rather than what is, envisioning a future filled with hope and possibility. Idealists are driven by their values and principles, striving to create positive change in society, whether through art, politics, or personal actions. In philosophy, idealism is a theory that suggests reality is fundamentally shaped by our thoughts and perceptions. Famous idealists like Immanuel Kant and George Berkeley argued that our understanding of the world is influenced by our mental constructs. This perspective encourages people to think deeply about their beliefs and the impact of their ideas on reality.
