The term "anthroposophy" was already used in early modern times. In an anonymous book entitled Arbatel de magia veterum, summum sapientiae studium (1575), attributed to the philosopher and theologian Agrippa von Nettesheim, anthroposophy (like theosophy) is attributed to the "science of good" and translated as "knowledge of natural things" or "prudence in human affairs". In 1648 the Anthroposophia Theomagica of the Welsh philosopher Thomas Vaughan appeared.
At the beginning of the 19th century, the Swiss physician and philosopher Ignaz Troxler (1780-1866) coined the term "anthroposophy" in reference to his Biosophy (Elements of Biosophy, 1806). In the sense of the forerunners of the philosophy of life, especially the natural philosopher Schelling, under whom Troxler had studied, biosophy was to mean "knowledge of nature through self-knowledge". Troxler called the knowledge of human nature anthroposophy. According to him, philosophy - and all philosophy is knowledge of nature - must become anthroposophy. This is presented as an "objectified anthropology" which is to start from the "original human being". In human nature, therefore, God and the world unite in a mystical process.
Immanuel Hermann Fichte also used the word anthroposophy in 1856 in Anthropology - The Doctrine of the Human Soul, referring to a "thorough self-knowledge of the human being" that lies "only in the exhaustive recognition of the spirit". However, the "human spirit" could not know itself in a truly thorough or fathoming way without thereby becoming aware of the "presence or proving of the divine spirit in it".
The philosopher of religion Gideon Spicker, who aspired to a "religion in philosophical form on a scientific basis" and regarded the conflict between faith and knowledge, between religion and natural science, as the basic problem of his life and thought, formulated the programme of an anthroposophy, also in the sense of "highest self-knowledge". Spicker's ideal embraced in religion the unity of God and the world as self-responsible knowledge using reason and experience.
The Austrian philosopher and herbartian Robert Zimmermann (1824-1898), creator of the "Philosophical Propaedeutics", chose the term "anthroposophy" in 1882 as the title of a pamphlet that sought to describe a system of ideal worldview on a realistic basis (Anthroposophy in Outline, 1882). Zimmermann, with whom Steiner listened to philosophy lectures, wanted in his system to go beyond the "barriers and contradictions inherent in the common standpoint of experience" and to establish a "philosophy of human knowledge" which, as a science, proceeds from experience but reaches beyond it where logical thinking requires it.
Rudolf Steiner initially used the name "anthroposophy" in a very free way. In 1902, for example, he gave a series of lectures in the Berlin literary circle he led, Die Kommenden, entitled: Von Zarathustra bis Nietzsche. History of the Development of Mankind on the Basis of World Views from the Most Ancient Oriental Times to the Present, or Anthroposophy. Nothing more is known about the content of these lectures. At the same time, he spoke publicly for the first time (within the framework of the Giordano Bruno Association) about the theosophy he represented from then on (title: Monism and Theosophy), whereby he linked up with Immanuel Hermann Fichte in terms of content. Within the framework of the Theosophical Society, Steiner used the term "anthroposophy" for the first time in 1909, namely for an extended sense doctrine. This he placed alongside the already existing theosophy, "similar to the way anthropology was placed alongside theology in the Middle Ages" (Anthroposophy, Psychosophy, Pneumatosophy, GA 115). After he had called a historical consideration of world views "Anthroposophy" in 1902, he now developed a sense doctrine under the same name, which supplemented the known five senses by five further senses and was thus to form a bridge between theosophy and anthropology. Concerning the history of the word, he remarked: "The word has already been used once. Robert Zimmermann wrote an anthroposophy, but he undertook it with most inadequate means [...]. He spun it out with the most exhausted, abstract concepts, and this gossamer was then his anthroposophy." Steiner did not finish a written version of his "anthroposophical" theory of the senses; it was published posthumously as a fragment (Anthroposophy - a Fragment, GA 45).
When in 1913 there was a break with the Theosophical Society and Steiner had to choose a new name for what he had hitherto represented as "Theosophy", he decided on "Anthroposophy".
