"What can we do? How can we act? How do we invite action?" These are some of the questions asked during the presentation of the Biennial of Thought, which for ten years now—this being its fifth edition—has turned Barcelona's public squares into a place for debate and reflection. In an increasingly dark world, ideas are more welcome than ever, and this year the reflections do not aim to be nostalgic or apocalyptic, but rather aspire to focus on the present with the motto "Unleashing the present".
