大衛R•霍金斯，美國著名心理學博士、精神治療師，入選《美國名人錄》，並經常在全美的電視節目“麥剋尼爾和萊爾新聞小時”、“芭芭拉•沃特秀”和“今日秀”上露麵。

霍金斯博士是美國精神病學會的終身會員，於1952年就開始從事精神病學治療。他曾跟諾貝爾奬得主萊納斯•鮑林閤著瞭富有創新性的《分子行為精神病學》。

霍金斯博士經過30年長期的臨床實驗，橫跨美國、加拿大、墨西哥、南美、北歐等地，隨機選擇測試對象，包括各種不同種族、文化、行業、年齡，纍積瞭幾韆人次和幾百萬筆數據，經過精密的統計分析之後，發現人類各種不同的意識層次都有其相對應的能量層級，依據此，繪就震撼世界的“意識能量層級圖譜”！

他有兩大突破，第一、將道德、精神層麵的領域引入科學實驗階段；第二、可以明確區分精神層麵內涵的好壞，並給予數值比較。例如，寬容、勇氣都帶來正麵能量，而寬容的能量比勇氣更強，但兩者都比憤怒要好。

因為本書，霍金斯博士被丹麥皇室封為爵士。
