Tertius Interveniens, written in 1610, is one of Kepler's most powerful and passionate treatises on astrology, written as a defence of the subject against extremists on both sides, on the one hand those who would condemn astrology altogether, and on the other those who accepted everything said and done in its name, no matter how preposterous. Hence he is the ‘third party intervening’, as indicated by the title.
