A partir da participacao no curso de extensao Tribuna do Cretino, quando discutimos a critica artistica, pretende-se caracterizar tres criterios fundamentais para o reconhecimento de uma obra artistica, com base em principios de Georg Wilhelm Friedrich Hegel (1770-1831), na tentativa de promover a interacao artista e publico, valorizando o oficio e os profissionais da area, sem limitar as producoes de arte em seus diversos suportes. Descreve-se as definicoes da origem, conteudo, finalidade e capacidade de transmissao de mensagens de uma obra qualquer, ao discutir-se relacoes entre a criacao do senso comum e o inedito, considerando o carente dialogo junto aos consumidores de arte, cuja problematica precisa ser superada. Espera-se contribuir para a uniao sensivel e racional, bem como o desenvolvimento de uma pratica artistica contra o atual cenario banalizante e danoso para o espirito humano, com significativa falta de comunicacao artistico-cultural e pouco entendimento para que serve a arte.

RATIONALIZATION OF ARTS FOR THE 21ST CENTURY Abstract: In order to characterize three fundamental criteria for the recognition of an artistic work, based on the principles of Georg Wilhelm Friedrich Hegel (1770-1831), when discussing artistic criticism during the course Tribuna do Cretino, this essay was produced. As an attempt to promote the artist and public interaction, valuing the craft and professionals of the area, without limiting the production of art in its most diverse supports. It is defined as the origin, content, purpose, and ability to transmit messages of any artwork, when discussing the relations between new creation and reality, considering the lack of dialogue with the consumers of art. It is hoped to contribute to the union of the sensible and rational, as well as the development of an artistic practice against the current banalizing and damaging scenario for the human spirit, with a significant lack of artistic-cultural communication and little understanding for what serves the art. Keywords : Communication. Visual arts. Art criticism.
