"When an appearance is given us, we are still quite free as to how we should judge the matter. The appearance depends upon the senses, but the judgment upon the understanding; and the only question is whether in the determination of the object there is truth or not."

I agree that we observe something, perceive it, and make a judgement. We understand that thing to the best of our ability, and I don't think anyone truly knows the truth about it. We can research, observe, and declare things as they are from what we know, but does anybody really know the truth about anything? I'm just not sure.
