Leonardo Da Vinci Quotes

Learning never exhausts the mind. I have been impressed with the urgency of doing. Knowing is not enough; we must apply. Being willing is not enough; we must do. The noblest pleasure is the joy of understanding. There are four powers: memory and intellect, desire and covetousness. The two first are mental and the others sensual. The three senses sight, hearing, and smell cannot well be prevented; touch and taste not at all. Experience never errs; it is only your judgements that err by promising themselves effects such as are not caused by your experiments. Simplicity is the ultimate sophistication. Although nature commences with reason and ends in experience, it is necessary for us to do the opposite, that is to commence with experience and from this to proceed to investigate the reason. All our knowledge has its origins in our perceptions. Time stays long enough for anyone who will use it. All knowledge which ends in words will die as quickly as it came to life, with the exception of the written word: which is its mechanical part. Life well spent is long. Poor is the pupil who does not surpass his master. It had long since come to my attention that people of accomplishment rarely sat back and let things happen to them. They went out and happened to things. Knowledge of the past and of the places of the earth is the ornament and food of the mind of man. The truth of things is the chief nutriment of superior intellects. Just as food eaten without appetite is a tedious nourishment, so does study without zeal damage the memory by not assimilating what it absorbs. Common sense is that which judges the things given to it by other senses. A beautiful body perishes, but a work of art dies not. The human foot is a masterpiece of engineering and a work of art. Nothing strengthens authority so much as silence Men of lofty genius when they are doing the least work are most active. Just as courage imperils life, fear protects it. Blinding ignorance does mislead us. O! Wretched mortals, open your eyes! As a well-spent day brings happy sleep, so a life well spent brings happy death. A painter should begin every canvas with a wash of black, because all things in nature are dark except where exposed by the light. The painter has the Universe in his mind and hands. Art is never finished, only abandoned. Realize that everything connects to everything else. The greatest deception men suffer is from their own opinions. Nothing can be loved or hated unless it is first understood. Study without desire spoils the memory, and it retains nothing that it takes in. You do ill if you praise, but worse if you censure, what you do not understand. Make your work to be in keeping with your purpose. Every action needs to be prompted by a motive. The deeper the feeling, the greater the pain.
