This article discusses the relationship between poetry and political subjectivity and the problems of justice and collective responsibility from an interdisciplinary approach, drawing on contributions from the fields of literature, history, philosophy and psychoanalysis. For this we have selected a poem by Victor Jara to show that poetry presents the construction of a political subject that reinforces the importance of justice and collective responsibility. This message is especially relevant today, in the context of the outstanding debts of the current democracy in relation to impunity and human rights. The method to approach these poetic texts is a semiotic analysis, which is linked to the national contexts in which they were produced.
