Final answer:
Jase's next step in critical thinking would be to assess the premise's truth, check facts, consider exceptions, and evaluate counterarguments.
Step-by-step explanation:
When Jase thinks critically about the claim his friend made, his next step in the process is likely to assess the truth of the premises. If the logic in the argument seems good, this involves looking for weaknesses in the premises. Jase will need to check the facts if the evidence is empirical; consider possible exceptions if the evidence is a principle; or contemplate potential counterexamples if the evidence is a conceptual claim.
Another key component in this process is the concept of epistemic humility, recognizing the limitations and conditionality of human knowledge. Jase might also benefit from adopting a stance that opposes his original position to generate counterarguments, thus enhancing his understanding of the opposing viewpoint.
