Love both?

"We must love them both, those whose opinions we share and those whose opinions we reject, for both have labored in the search for truth, and both have helped us in finding it." ~ Thomas Aquinas
 
Cause and effect? By loving both I find the Truth, or by joyfully accepting opposing points of view I accept the Oneness behind the pinions? The Truth is in loving both? As long as I accept an opinion as true, or reject an opinion as untrue, I continue to express preference within duality. My grimly held opinions are barriers to love. Nagarjuna gently reminds me: What I believe is neither True nor not True....
Love, Diederik
