The preceding Arcanum – ‘The Moon’ – confronted us with the task of human intelligence to liberate itself from the magical enchantment which separates it from spontaneous wisdom, and to unite itself with the latter, ie, to arrive at intuition. The nineteenth Arcanum – “The Sun” – is that of the accomplished union of intelligence and spontaneous wisdom: the Arcanum of intuition.
“The children who are fraternising under the sun correspond all the better to Gemini because this zodiacal constellation berings in the longest days to us” says Oswald Wirth (Le Tarot des imagiers du moyen age), thus locating the nineteenth Arcanum in the zodiacal circle of twelve cosmic mysteries or, speaking in the language of C J Jung, in the circle of twelve archetypal force-images of the collective unconscious which work in the depths of every human soul.
For the zodiac is that which the human soul knows unconsciously; it is the book which the soul “ate” and which is present and active only in his “bowels” – in the depths of his being – from whence it renders him strong or weak, fertile or arid, fervent or tepid, according to whether he is in harmony or not with its teaching-impulse.
Now, the teaching impulse called “Gemini” can be expressed by paraphrasing a little the first statement of the Emerald Table of Hermes:
This is the principle of analogy put into practice, taking its point of departure from the principle of cooperation.
One of the highest aspects of the principle of Gemini, the principle of cooperation, is that which is present in intuition: that of the cooperation between spontaneous wisdom and intelligence. Here it is a matter of a state of consciousnes where intelligence advances from formal knowledge to material knowledge, ie, from knowledge of the relationships of the things to knowledge of the things themselves.
