All or nothing

We need not know all truth, or even a good deal of truth in order to know some truth. For example, I do not need to know what 4x4 is to know that 2+2 is 4, or how to use that truth. We can easily get distracted by clever arguments that tell us that because we do not understand the implications of a truth we claim to know, or how other truths might inform a more complete view of our known truth, we do not really know what is true. In other words we can be questioned into a less confident claim on truth. This tactic seems to be one of the most common, and perhaps effective tactics in separating us from a given truth.

This might have something to do with our crisis of trust. That is a topic for much later.
