Paracelsus was born near [Zurich] in 1493. His father was a country [physician] with an interest in alchemy which he shared with his son, who would later become the first proponent and theorist of [iatrochemistry].

Paracelsus left home to study when he was 14, and traveled widely as a student and later as a roaming physician. It is certain that he studied for some time with [Johannes Trithemius], and also that he held a high opinion of himself, particularly in comparison with the [academic|academics] and academic physicians for whom he often expressed a scathing and witty [contempt]. His abrasive demeanor and rash temper caused him to lose position after position, and stay on the move. He died in 1541 in [Salzburg]. Though he was well enough known to be a controversial figure, few of his writings were published while he was alive.

After his death, Paracelsus' writings came to be widely published, and a school of sympathetic thinkers coalesced around his work. The Paracelsians extended Paracelsus' antipathy for academia into their articulation of [natural philosophy], and rejected the dominant Aristotelian paradigm as antiquated [jalopy|theory] constructed of paganism, strange mathematics, and philosophical baling wire. This rejection of Aristotelian thought led quite naturally to their concurrent rejection of [Galen]. This picture is not held unequivocally by historians, however, some of whom envision Paracelsian thought as a synergy of Galenic theory (appropriated in a kind of hostile take-over, but appropriated rather than rejected nonetheless) and [mysticism|medieval German mysticism]. There is textual foundation for this interpretation as well, as it appears that Paracelsus (while firmly committed to integrating [Reformation|Reformationist] [theology] with his science) was actively engaged in [alchemy|alchemical] and [magic|magical] study - and may have even thought of himself as a kind of magus.

Paracelsus' characteristic refusal to participate in neat self-compartmentalization extended to his practice of speaking in scathing terms about Aristotelians and Galenists while retaining some aspects of their philosophy to bulwark his own. Whether or not [push me, pull me|these acts of concurrent acceptance and rejection] constitute a coherent program of response to his ancients and contemporaries is debatable, but it was certainly a common enough trope in his work. For example, his generally negative assessment of mediaeval alchemists sits strangely with his use of [John of Rupescissa|Rupescissian] and Lullian methods for extracting [quintessence], or [ethyl alcohol], from various substances. Paracelsus' philosophy is not always consistent, sometimes contradictory, and challenges the modern reader to read without seeking after for modern coherencies at the expense of medieval coherencies.
