Vertical and horizontal lines are the expression of two opposing forces; they exist everywhere and dominate everything; their reciprocal action constitutes 'life'. I recognized that the equilibrium of any particular aspect of nature rests on the equivalence of its opposites.

'Masculine and feminime, vertical and horizontal.

I believe that it is possible by means of horizontal and vertical lines, constructed 'consciously' but not 'calculating', guided by a higher intuition and brought to harmony and rhythm – I believe that these fundamental aesthetic shapes – where necessary supplemented by lines in other directions or curved lines, make it possible to arrive at a work of art which is as strong as it is true. For anyone who sees more deeply, there is nothing vague about this; it is only vague for the superficial observer of nature. And 'chance' must be as far removed as 'calculation'. And for the rest it seems to me that it is necessary to keep breaking off the horizontal or vertical line: for if these directions were not countered by others, they would themselves come to signify something 'specific' and thus human.

Allow me to repeat what I said when you were here: deal with nature by means of the cylinder, the sphere and the cone, all placed in perspective, so that each side of an object or a plane is directed towards a central point. Lines parallel to the horizon give breadth, a section of nature, or if you prefer, of the spectacle spread before our eyes by the 'Pater Omnipotens Aeterne Deus'. Lines perpendicular to that horizon give depth. But for us men, nature has more depth than surface, hence the need to introduce in our vibrations of light, represented by reds and yellows, enough blue tints to give a feeling of air.

The straight line belongs to Man. The curved line belongs to God.

The vertical is in my spirit. It helps me to define precisely the direction of lines, and in quick sketches I never indicate a curve, that of a branch in landscape for example, without being aware of its relationship to the vertical. My curves are not mad.

Treat nature in terms of the cylinder, the sphere, and the cone, the whole put into perspective so that each side of an object, or of a plane, leads towards a central point. Lines parallel to the horizon give breadth, whether a sections of nature, or, if you prefer, of the spectacle which Pater omnipotens aeterne Deus unfolds before your eyes. Lines perpendicular to this horizon give depth.. .Everything I am telling you [ Joachim Gasquet ] about - the sphere, the cone, cylinder, concave shadow – on mornings when I'm tired these notions of mine get me going, they stimulate me, I soon forget them once I start using my eyes.

Like the ocean, the native state of the feminine is to flow with great power and no single direction. The masculine builds canals, dams, and boats to unite with the power of the feminine ocean and go from point A to point B. But the feminine moves in many directions at once. The masculine chooses a single goal and moves in that direction. Like a ship cutting through a vast ocean, the masculine decides on a course and navigates the direction: the feminine energy itself is undirected but immense, like the wind and deep currents of the ocean, ever changing, beautiful, destructive, and the source of life.

La verticale est dans mon esprit. Elle m'aide à préciser la direction des lignes, et dans mes dessins rapides je n'indique pas une courbe, par exemple, celle d'une branche dans un paysage, sans avoir conscience de son rapport avec la verticale. Mes courbes ne sont pas folles.

He always thought of the sea as la mar, which is what people call her in Spanish when they love her. Sometimes those who love her say bad things of her, but they are always said as though she were a woman. Some of the younger fisherman, those who used buoys as floats for their lines or had motorboats bought when the shark lovers had much money, spoke of her as el mar, which is masculine, they spoke of her as a contestant or a place or even an enemy. But the old man always thought of her as feminine, as something that gave or withheld great favors. If she did wild or wicked things, it is because she could not help them. The moon affects her as it does a woman, he thought.

Always lines, never forms. Where do they find these lines in Nature? Personally I see only forms that are lit up and forms that are not, planes that advance and planes that recede, relief and depth. My eye never sees outlines or particular features or details... ...My brush should not see better than I do. [Goya, in a recall of an overheard conversation]

Approaching it in one way, I see no essential difference between a line one calls 'abstract' and a 'fish'. But rather an essential likeness. This isolated line and the isolated fish alike are living beings with forces peculiar to them, though latent. They are forces of expression for these beings and of expression on human beings, because each has an impressive 'look' which manifests itself by its expression. But the voice of these latent forces is faint and limited. It is the environment of the line and the fish that brings about a miracle: the latent forces awaken, the expression becomes radiant.. .The environment is the composition. The composition is the organized sum of the interior functions (expressions) of every part of the work.

As you can see this is a composition of vertical and horizontal lines which will (in an abstract manner) have to express the idea of rising upwards, of magnitude. This is the same idea which used, for example, to be the guiding principle in the construction of cathedrals. Since only the manner of expression and not the representation has to express this general idea, I have not given any title. An abstract human mind will, of itself, receive the intended impression. I always confine myself to expressing the general.
