Final answer:
The trilogy of consistency proposed by Van Epp consists of consistency, coherency, and non-contradiction, which are essential characteristics for creating a solid and logical framework in various disciplines.
Step-by-step explanation:
The trilogy of consistency, as proposed by Van Epp, includes the following characteristics: consistency, coherency, and non-contradiction. Each of these elements helps to establish a solid and logical framework that can be applied to various concepts, including psychological theories, literary analysis, and even biology. For instance, Van Epp emphasizes the importance of consistency in relationships, theories, and narratives, ensuring that patterns of behavior or thought maintain a certain level of predictability over time. Coherency is the quality of being logical and consistent, which helps to strengthen arguments or narratives by ensuring that they make sense and that each part contributes to the whole in a meaningful way. Non-contradiction further underscores the importance of internal logical consistency; this principle asserts that a theory or narrative should not contain conflicting statements or ideas that would undermine its validity. These principles create a framework for analyzing and constructing robust arguments and narratives, and they can be considered foundational for critical thinking and reasoning across multiple domains.
