idealismia
Idealismia is a philosophical concept that posits reality is fundamentally mental, conceptual, or based on ideas. This stands in contrast to materialism, which asserts that only matter is real. Idealists believe that consciousness, mind, or spirit is primary, and the physical world is either a manifestation of or dependent upon this mental realm. There are various forms of idealism, including subjective idealism, where reality is dependent on individual minds, and objective idealism, where reality is a manifestation of a universal or absolute mind. Plato's theory of Forms is often cited as an early example, suggesting that physical objects are imperfect copies of eternal, perfect abstract Forms. George Berkeley, a prominent proponent of subjective idealism, argued that "to be is to be perceived" (esse est percipi), meaning objects only exist when they are being observed by a mind. Immanuel Kant proposed transcendental idealism, distinguishing between the phenomenal world (the world as we experience it) and the noumenal world (the world as it is in itself, which is unknowable). The implications of idealism can extend to areas such as epistemology, ethics, and aesthetics, influencing how we understand knowledge, values, and beauty.
