What philosophical position asserts that objects exist independently of an observer?

The philosophical position that asserts objects exist independently of an observer is realism. This view maintains that the world exists independently of our perceptions, beliefs, or consciousness. Realism holds that there are objective truths about the world that can be discovered through observation and scientific inquiry. This contrasts starkly with positions such as idealism, which argues that objects do not exist independently of perception, and constructivism, which focuses on how knowledge is constructed rather than uncovered. Critical realism introduces a nuanced view that acknowledges the influence of human perception on the understanding of reality, while still affirming the existence of a reality independent of our experiences. Therefore, realism is the most fitting answer as it unequivocally states that the existence of objects is not contingent upon an observer's perception.
