Problem: Please answer a question about the following article about Humanism:
At about the same time, the word "humanism" as a philosophy centred on humankind (as opposed to institutionalised religion) was also being used in Germany by the so-called Left Hegelians, Arnold Ruge, and Karl Marx, who were critical of the close involvement of the church in the repressive German government. There has been a persistent confusion between the several uses of the terms: philanthropic humanists look to what they consider their antecedents in critical thinking and human-centered philosophy among the Greek philosophers and the great figures of Renaissance history; and scholarly humanists stress the linguistic and cultural disciplines needed to understand and interpret these philosophers and artists.
Who did benevolent believers in humanism turn to for ideas about the philosophy?
A: Greek philosophers
