Observers cannot remove themselves from their observations and judgements

Polanyi argued that all knowing is personal, and as such relies upon fallible commitments. Our skills, biases, and passions are not flaws but play an important and necessary role in discovery and validation. Observers cannot remove themselves from their observations and judgements, nor should they; it is enough that we act in accordance with the consequences imposed upon us by our beliefs.

What saves this claim from relativism is his belief that our tacit awareness connects us with realities, although as our tacit awareness relies upon assumptions acquired within a local context, we cannot simply assume that they have universal validity; we must rather be open to the possibility of error while seeking to identify objective truths. Any process of articulation, however, inevitably relies upon that which we have not articulated. Indeed, reliance upon what we have not articulated is how words become meaningful, i.e. meaning is not reducible to a set of rules; it is grounded in our experience of the world - where experience is not something that can simply be reduced to collections of sense data.
