Paralogize means to reason or argue illogically. Its antonyms are terms that represent the opposite meaning such as rationalize, justify, and substantiate. Rationalize means to provide logical or fair reasons for something, and justify means to prove or show that something is right or reasonable. On the other hand, substantiate means to provide solid evidence to support an argument or claim. By using these antonyms in the right way, we can avoid paralogizing and make sound judgments based on evidence and logic. Ultimately, developing a strong understanding of these words will help us become better critical thinkers and communicators.
