Description provided by the artist: 'The pH Gender Scale measures how gendered a social structure or a cultural production is. The more it tends to the acid, the more gendered the sample is. Taking as sample the Ideological State Apparatuses and the Repressive State Apparatus suggested by Althusser, the French Marxist philosopher, as well as his .essay 'Ideology and Ideological State Apparatuses (Notes towards an Investigation)', .(1970), the pH Gender Scale depicts how highly gendered they are. Through this illustration, it is communicated the fallacy of the gender neutrality of the .social reality.'. .This artwork is part of the project Footnotes on Equality: http://footnotesonequality.eu/all/
