In 1949, the young Orlando Fals Borda had his first contact with the village of Saucío in the department of Cundinamarca. A cultural, rural and Andean landscape – so different from his – that would be the epicenter of his sociological reflection. Known for being one of the most outstanding Colombian intellectuals in history, Fals Borda practiced, theorized and taught until the end of his days the concept of “sentipensante” to define social research from a respectful, empathetic and committed perspective with communities. The 72 photographs included in this book are part of the field diary of that first experience in Saucío. Far from hierarchies and manichaeisms, the images that make up this book give an account of the gaze of a sensitive and original photographer, who dignifies the human condition and values the work, daily life, affections and temperance of the popular sectors of rural Colombia in the first half of the twentieth century.
