Former Senegal president and head of the Socialist Party of Senegal Leopold Senghor and anti-colonial Africanist writer Chinua Achebe have criticised the slogan as being a limited and Eurocentric view on art and creation. Senghor argues that, in "black African aesthetics," art is "functional" and that in "black Africa, 'art for art's sake' does not exist." Achebe is more scathing in his collection of essays and criticism entitled "Morning Yet on Creation Day", in which he asserts that "art for the sake of art is just another piece of deodorised dog shit ."
