Post-Truth çağda figüratif resim ve heykel

Ataş, Eyüp

Hakikatin önemsizleştiği post-truth dönemde insanlık bir simülasyon çağı yaşamaktadır. Zaman ve mekân algısı değişmiş, görüntülerden oluşan sanal bir imgelem dünyası söz konusu olmuştur. Artık her şey sayılardan oluşan bir veridir. Her türlü hakikat her an değişebilir durumdadır. Bu dönemde sanal medya kullanıcıları herhangi bir alandaki yeterliliklerine bakılmaksızın ‘her şey’ olabilmektedir.

The impacts of poststructuralism, psychoanalysis and postmodernism on the development of autofiction

Önder, Ayda

This study aims to investigate the ways in which poststructuralism, psychoanalysis and postmodernism have contributed to the development of autofiction.

Autofiction both affirms and questions the poststructuralist dismantling of the traditional perspectives on the concepts of authority, authenticity and truth by bringing the authorial presence back to the text but fictionalising it to some extent, committing to narrate the truth but creating an ambivalence around it. Autofiction engages ...Daha fazlası
