"It is one of the aims of linguistics to define itself, to recognise what belongs within its domain. In those cases where it relies upon psychology, it will do so indirectly, remaining independent"

This quote by Ferdinand De Saussure speaks to the significance of linguistics as a discipline. He stresses the need for linguistics to define itself and acknowledge what falls within its domain. He likewise suggests that linguistics must stay independent from psychology, even when it relies on psychological concepts. This suggests that linguistics should be viewed as an unique discipline, with its own set of concepts and methods. It is necessary for linguistics to keep its independence from other fields, as this allows it to establish its own special theories and methods. By doing so, linguistics can stay an unique discipline, and can continue to make essential contributions to our understanding of language.
