and colours, he substantiated the universality of shapes in his artworks thus paving the way for further abstraction. Wassily Kandinsky often used black in his paintings to heighten the impact of brightly coloured forms while his forms were often biomorphic approaches to bring surrealism in his art. Theoretical writings on art Kandinsky's analyses on forms and colours result not from simple, arbitrary idea-associations but from the painter's inner experience. He spent years creating abstract, sensorially rich paintings, working with form and colour, tirelessly observing his own paintings and those of other artists, noting their effects on his sense of colour. This subjective experience is something that anyone can do—not scientific, objective observations but inner, subjective ones, what French philosopher Michel Henry calls "absolute subjectivity" or the "absolute phenomenological life". Concerning the spiritual in art Published in Munich in 1911, Kandinsky's text, Über das Geistige in der Kunst, defines three types of painting; impressions, improvisations and compositions. While impressions are based on an external reality that serves as a starting point, improvisations and compositions depict images emergent from the unconscious, though composition is developed from a more formal point of view. Kandinsky compares the spiritual life of humanity to a pyramid—the artist has a mission to lead others to the pinnacle with his work. The point of the pyramid is those few, great artists. It is a spiritual pyramid, advancing and ascending slowly even if it sometimes appears immobile. During decadent periods, the soul sinks to the bottom of the pyramid; humanity searches only for external success, ignoring spiritual forces. Colours on the painter's palette evoke a double effect: a purely physical effect on the eye which is charmed by the beauty of colours, similar to the joyful impression when we eat a delicacy. This effect can be much deeper, however, causing a vibration of the soul or an "inner resonance"—a spiritual effect in which the colour touches the soul itself. "Inner necessity" is, for Kandinsky, the principle of art and the foundation of forms and the harmony of colours. He defines it as the principle of efficient contact of the form with the human soul. Every form is the delimitation of a surface by another one; it possesses an inner content, the effect it produces on one who looks at it attentively. This inner necessity is the right of the artist to unlimited freedom, but this freedom becomes licence if
