The purpose of this paper is to compare two studies concerning the linguistic action of referring; on the one hand, the proposal of Peter Strawson who introduces the notion of expression and, on the other hand, that of Hansjakob Seiler who proposes the notion of dimension of Identification. The first occurs within philosophy and the second within linguistics. The purpose of this comparison is to point out, albeit in a hypothetical and incipient manner, that with the merger of these two proposals a new perspective would be achieved through which some problems on the subject of reference can be addressed, confronted and solved. However, the latter is not developed, since this paper only focuses on highlighting certain similarities and differences between these two proposals.
