Dreams + Disillusions explores the plethora of ideas and ideologies that have shaped and reshaped cities in profound ways. However, unlike a conventional title on the history of urbanism and architecture, its research fluctuates between the world of concrete reality and the multiple universes that exist in lucid prose, poetic visions, and the outrageous imaginations of history’s greatest and most (in)famous minds. In their thoughts are the foundations for political trends and new civilisations, alternative mappings and unlikely phenomena. The six chapters reveal dreams that were fundamental to the origin of great cities, underpinning the stories of the many lives within; and how, through circumstance or manipulation, fortunate coincidence or planned perfection, desires are sometimes left defeated and disillusioned.Myth and belief. Tradition and logic. Revolution and marginalisation. Ignorance and hubris. Sins and excess. Seasons and climate. Continuously interacting, shifting to enlighten and to enrage, these themes combine critical thinking with deep-rooted influences and new agencies that are a true sign of the times. The 18 illustrated speculations provide an abundance of curious imaginings, diverse provocations and satirical criticism. While there are distinctions between dreams and disillusions, could virtues be made of sins, or sensitivity be borne from hubris? Could progress advocate tradition, or should we re-attempt revolutions formerly experienced as disillusionments? Whether by bold gestures or by subtle attrition, cities are continually re-written crucibles for the human condition. In this book, we develop a better understanding of the discourse of cities tailored to the determining factors of climate, resources, and humanity’s idiosyncrasies to address a world in crisis.
