Object level vs Meta level is a distinction between levels of abstraction, with the object level being directly about the specifics of the issue at hand, while meta level is concerned with the general principles which apply to a wider range of examples. It is often useful to move up and down the ladder of abstraction to get points across clearly, with the object level providing firm grounding and concrete examples for a person to grasp, while the meta layer allows them to generalize a new concept to a broad domain.
