"to reason from the ground up"-- to reason or argue with another as if there were no shared assumptions about significance or meaning.
dialogical character of human life-- humans are capable of understanding themselves only through the shared languages of human expression. Taylor includes in the notion of "language" the languages of art, culture, love, gesture, etc. Moreover, the acquisition of knowledge and experience here has an essential "dialogical" rather than "monological" character.
horizons-- the "background of intelligibility;" the "background against which our tastes and desires and opinions and aspirations make sense."
