Final answer:
Logical possibility sets the boundaries for consistent and coherent beliefs, highlighting the need for beliefs to be logically consistent to reflect reality accurately. Logic serves as a normative guideline in philosophy, emphasizing that reasoning should avoid contradictions. The distinction between logical necessity and actual existence is crucial in determining what truly exists in reality.
Step-by-step explanation:
What is logically possible provides insights into reality by setting boundaries for consistent and coherent beliefs. Philosophers make use of logic to ensure that their beliefs are internally consistent and avoid contradictions since a contradiction is a logical impossibility. If beliefs are not logically consistent, then at least some of the beliefs must be false. Logic, as a way of knowing, concerns itself with the form and structure of knowledge, emphasizing the importance of relationships among ideas.
Moreover, logic enforces the normative stance that one ought to avoid inconsistency in reasoning. The law of the excluded middle aids in this process by asserting that for any given statement, either the statement or its negation is true, maintaining that a statement cannot be both true and false. This foundational principle of logic serves as a guideline for evaluating the reality of our beliefs and claims. The necessity for beliefs to correspond to empirical facts and to cohere with accepted truths further grounds the necessity of logical consistency in describing reality.
Logical possibility does not entail the actual existence of a concept in reality, such as the notion of the Greatest Conceivable Being (GCB). Thinking logically about the GCB does not prove its existence in reality. It is, therefore, essential to distinguish between what is logically possible or necessary and what exists in reality, with the latter shaping our understanding of the world and its limitations based on our experiences.
