Practice should always be based upon a sound knowledge of theory.
Being engulfed in practice without delicate knowledge related to it, is in many ways like entering a ship without knowing where it is headed.
Science is the captain, and practice the soldiers.
It reflects no great honor on a painter to be able to execute only one thing well -- such as a head, an academy figure, or draperies, animals, landscapes, or the like -- in other words, confining himself to some particular object of study. This is so because there is scarcely a person so devoid of genius as to fail of success if he applies himself earnestly to one branch of study and practices it continually.
Those who fall in love with practice without science are like a sailor who enters a ship without a helm or a compass, and who never can be certain whither he is going.
First study the science, and then practice the art which is born of that science.
The painter who draws merely by practice and by eye, without any reason, is like a mirror which copies every thing placed in front of it without being conscious of their existence.
Those who are in love with practice without knowledge are like the sailor who gets into a ship without rudder or compass and who never can be certain whether he is going. Practice must always be founded on sound theory, and to this Perspective is the guide and the gateway; and without this nothing can be done well in the matter of drawing.
Those who are enamoured of practice without science are like a pilot who goes into a ship without rudder or compass and never has any certainty of where he is going. Practice should always be based upon a sound knowledge of theory.
There shall be wings! If the accomplishment be not for me, 'tis for some other.
Obstacles cannot crush me; every obstacle yields to stern resolve.
Nothing can be love or hated unless it is first known.
When once you have tasted flight, you will forever walk the earth with your eyes turned skyward, for there you have been, and there you will always long to return.
Experience does not ever err; it is only your judgment that errs in promising itself results which are not caused by your experiments
