What does realism assert about truth?

Realism asserts that truth exists as an objective reality that does not change, which aligns with the philosophical stance that an objective, independent reality exists outside human perception and interpretation. This viewpoint maintains that there are facts about the world that are true regardless of individual beliefs or feelings. For instance, in the context of scientific inquiry, realism supports the idea that discoveries about natural phenomena (like gravity or the laws of thermodynamics) are truths that exist independently of whether people recognize or accept them.

In contrast, the other options suggest varying degrees of subjectivity or social construction. The notion that truth is subjective or dependent on individual experiences directly opposes the realist perspective, which emphasizes an unchanging, objective reality. Additionally, the idea that truth is constructed through social interactions aligns more closely with social constructivism, which posits that our understanding of truth is shaped through contexts and relationships rather than existing independently. Therefore, the assertion that truth is an unchanging and objective reality is what solidifies the selection of this answer.
