Context: It is surprising to me to see how many people separate the objective from the abstract. Objective painting is not good painting unless it is good in the abstract sense. A hill or tree cannot make a good painting just because it is a hill or a tree. It is lines and colours put together so that they say something. For me that is the very basis of painting. The abstraction is often the most definite form for the intangible thing in myself that I can only clarify in paint. … I found I could say things with color and shapes that I couldn't say any other way — things I had no words for.<!-- Also quoted in Georgia O’Keeffe: Nature and Abstraction (2007), edited by Richard Marshall, p. 13

Variant translation: Artificial flight may be defined as that form of aviation in which a man flies at will in any direction, by means of an apparatus attached to his body, the use of which requires the dexterity of the user.

Context: Artificial flight may be defined as that form of aviation in which a man flies at will in any direction by means of an apparatus attached to his body, the use of which requires personal skill. Artificial flight by a single individual is the proper beginning for all species of artificial flight, as the necessary conditions can most easily be fulfilled when man flies individually.
