Only a trained eye can see what is most important in the economy, society and politics. And yet, this truth is not obvious.

Bastiat’s observations are worth recalling especially today, when politicians who want to save the world do not understand that their actions have unforeseen, often negative consequences – explains Sebastian Stodolak, the author of a series of conversations with scientists, intellectuals and freedom activists.
