no ideas but in things

"Most people fail to see this reality, for they are attached to what they cling to, to pleasures and delights. Since all the world is so attached to material things, it's very difficult for people to grasp how everything originates in conditions and causes. It's a hard job for them to see the meaning of the fact that everything, including ourselves, depends on everything else and has no permanent self-existence."

-- Majjhima Nikaya
