핵심 특성
주요 업적
조선 후기 실학자인 그는 통치, 법, 유교 경전에 관한 저술을 남겼으며, 그의 글은 사후 『여유당전서』 154권 76책으로 정리되어 1934~1938년에 간행되었다.
1801년 이후 강진 유배지에서 그는 지방 관리를 위한 48권의 지침서 『목민심서』를 1818년에 완성했고, 『경세유표』에서는 기술을 도입할 국가 관청 신설 등의 개혁을 제안했다.
정조 치하의 관리로서 그는 한강 배다리(1789)와 화성 축조(1792) 설계에 참여했고 거중기를 고안했으나, 한 역사학자는 실제 사용이 기록된 거중기가 한 대뿐이라고 지적한다.
삶의 장면들
거중기를 만들 때 그는 수입된 『기기도설』을 참고하되 철과 구리 사용을 줄이고 불필요한 조항을 덜어내 기본 원리에 집중했다.
이는 외부의 설계를 현지의 재료와 필요에 맞게 고쳐 쓰는 태도와 부합한다. 자원 활용 성향
그는 1818년 강진에서 자신의 지방관 경험을 바탕으로 48권 16책의 지방 행정 지침서 『목민심서』를 완성했다.
이는 실용을 목표로 한 꾸준하고 세밀한 저술과 부합한다. 끈기
전환점
1801년 박해 이후 그는 18년간 유배 생활을 했고 그중 11년을 강진 다산초당에서 보냈으며, 통치와 경전에 관한 그의 저술 대부분이 이 시기에 이루어졌다.
이는 관직 생활에서 꾸준한 학문 저술로 활동의 중심이 옮겨 갔음과 부합한다. 끈기
