Answer:
When reality is expressed in words, we call that "truth", an Ultimate truth would be something that will be true regardless of the circumstances which can't be changed; but people can perceive the same thing or event in a different way sometimes and then form an opinion.
According to Italian philosopher St. Thomas Aquinas, we should love both the opinions we share and also those whose opinions we repel or refuse.
Thus to ensure all viewpoints are considered and discover an "Ultimate Truth" we should embrace and come together with those whose opinions we refuse, spend time together and congregate to get ideal understandings.
