This work compares the perception of the social Valencianism of the 1930’s (basic aims: awareness of Valencianness and use of the Valencian language; secondary aim: linguistic coordination with the Balearic Islands and Catalonia, §2) with the perception that prevailed in the second half of the 20th century («the unity of the language» as a primary objective; the increase in the use of the language as a secondary objective). The reproduction and the analysis of a document from the second perception (§3) contributes to explain the relative degree of incidence that the unitarist Valencianism has had in the last decades and, correspondingly, it impels to reflect on the mistakes made by the Valencianism in the second half of the 20th century. The aim of self-criticism is to improve deficiencies in order to impact on the willingness to be Valencian and to grow the wish to recover the public use of the Valencian language.
