truth for us is always relative to that conceptual system

"Since we understand situations and statements in terms of our conceptual system, truth for us is always relative to that conceptual system. Likewise, since an understanding is always partial, we have no access to "the whole truth" or to any definitive account of reality." (#60 3077)
"The fact that our conceptual system is inherently metaphorical, the fact that we understand the world, think, and function in metaphorical terms, and the fact that metaphors can not merely be understood but can be meaningful and true as well—these facts all suggest that an adequate account of meaning and truth can only be based on understanding." (#60 3148)
"truth is relative to our conceptual system, which is grounded in, and constantly tested by, our experiences and those of other members of our culture in our daily interactions with other people and with our physical and cultural environments." (#60 3283)
