In Austrian philosopher/educator Rudolf Steiner's (1861–1925) thinking, spiritual emptiness was a major problem in the educated European middle class. In his 1919 lectures he argued that European culture became "empty of spirit" and "ignorant of the needs, the conditions, that are essential for the life of the spirit". People experienced a "spiritual emptiness" and their thinking became marked by a "lazy passivity" due to the "absence of will from the life of thought". In modern Europe, Steiner claimed that people would "allow their thoughts to take possession of them", and these thoughts were increasingly filled with abstraction and "pure, natural scientific thinking". The educated middle classes began to think in a way that was "devoid of spirit", with their minds becoming "dimmer and darker", and increasing empty of spirit.
