Fallacious energic formulations and phylogenetic oversimplifications have led drive theory into disfavor. However, the advantages of a drive concept based on evolutionary principles outweigh the disadvantages. A psychological drive concept best captures the innately endowed, self-enhancing motivational push compatible with evolutionary principles, while at the same time being consonant with the intrapsychic dynamics of psychoanalytic observation. Current evolutionary principles and their implications are discussed. Incorporating these principles as cogent theoretical postulates is a crucial part of maintaining a link to the natural sciences and thereby to our involvement in the great enterprise of elaborating a comprehensive psychology. To exclude these concepts is to promote a detachment from our involvement in the natural sciences and to lose a powerful heuristic guide for our theoretical endeavors.
错误的能量公式和系统发育的过度简化使驱力理论失宠。然而，基于进化原则的驱力概念的优点超过了缺点。一个心理驱力概念最能捕捉到与进化原则相一致的天生赋予的、自我增强的动机驱动力，同时又与精神分析观察的心理动力学相一致。本文讨论了当前的进化原则及其影响。将这些原则纳入有说服力的理论假设是与自然科学保持联系的关键部分，从而使我们参与到阐述全面心理学的伟大事业中。排除这些概念会促使我们脱离对自然科学的参与，并使我们在理论探索中失去一个强大的启发式指南。
