We use truth entirely objectively, but that's only because subjectively the verb "use" doesn't apply. In itself, truth is neither subjective nor objective--subjective and objective are views and attitudes that we take towards things. When we talk about objective, we are adopting the view of truth. Everything can be viewed objectively or subjectively--the "thing in itself" is neither.
The truth of the subjective is the truth about (for instance) what things mean to us uniquely, how we relate to them or how they relate to other things. Everything objective is, by definition, true and can be thrust into a proposition. If it's truth that, "I find that painting beautiful," that's objective. The subjective is the experience of meaningfulness and relating to a thing.
Without judgement, there is no life to talk about. But there is the experience of life.
