The author presents drawings made on the blackboard in front of his students at the university. This article aims to show the heuristic value of drawing in view of a human-oriented anthropology, i.e. focused on a human being, as detached as possible from other humans, situations or contexts. The drawings aim to illustrate the differences between ethnography and what he calls volumography, which focuses on the human being as a VoB. Throughout the article, the author discusses the notions of separation, perspective, and relation. In asking who is really describing this or that person in the spectrum of sciences, the author proposes that this task falls to existential anthropology.

作者在他的大学学生面前展示了在黑板上画的图画。本文旨在从以人为本的人类学角度展示绘画的启发式价值，即以人为中心，尽可能脱离其他人、情况或背景。这些图旨在说明人种学与他所谓的体量学之间的差异，体积学侧重于将人类作为 VoB。在整篇文章中，作者讨论了分离、透视和关系的概念。在询问谁真正描述了科学领域中的这个或那个人时，作者提出这项任务属于存在主义人类学。
