The lecture was quite interesting as it reminded me of a popular stance on Epicurus which is predominant in modern German literature. Epicurus is understood as a philosopher who reaches for inner independence while also granting enjoyment of pleasure as long as the enjoyment doesn't collide with freedom from pain. The focus is slightly different than that of the forum, as it traditionally centers the ethics and doesn't dig deeper. Physics and Canonics remain nearly untouched.
Nonetheless I was amazed by the quite remarkable volume Epicurus was granted by the speaker.
In the following discussion I asked what the reference of Humanism to Epicurus is and he indeed answered, that Epicurean Philosophy has many similarities to Humanism because of Materialism and a positive attitude towards life and the human being. But he also stated, that rather Cicero is seen as a father figure, refering to the term "humanitas" which he told had been coined by Cicero.
I also asked what Humanism is, and they answered that it's about focussing on the human being and individuality. Speaking from the point of being an organisation, they don't want to be critics of religion but form a secular alternative, giving positive value in the world.
I would definitely see them as allies, but I also recognise them as focused more on societally tasks than promoting the personal transformation through philosophy which I regard as the key point.
