大卫R•霍金斯，美国著名心理学博士、精神治疗师，入选《美国名人录》，并经常在全美的电视节目“麦克尼尔和莱尔新闻小时”、“芭芭拉•沃特秀”和“今日秀”上露面。

霍金斯博士是美国精神病学会的终身会员，于1952年就开始从事精神病学治疗。他曾跟诺贝尔奖得主莱纳斯•鲍林合著了富有创新性的《分子行为精神病学》。

霍金斯博士经过30年长期的临床实验，横跨美国、加拿大、墨西哥、南美、北欧等地，随机选择测试对象，包括各种不同种族、文化、行业、年龄，累积了几千人次和几百万笔数据，经过精密的统计分析之后，发现人类各种不同的意识层次都有其相对应的能量层级，依据此，绘就震撼世界的“意识能量层级图谱”！

他有两大突破，第一、将道德、精神层面的领域引入科学实验阶段；第二、可以明确区分精神层面内涵的好坏，并给予数值比较。例如，宽容、勇气都带来正面能量，而宽容的能量比勇气更强，但两者都比愤怒要好。

因为本书，霍金斯博士被丹麦皇室封为爵士。
