Art is never finished, only abandoned. - Leonardo da Vinci

"Study without desire spoils the memory, and it retains nothing that it takes in."

"Truth at last cannot be hidden. Dissimulation is of no avail. Dissimulation is to no purpose before so great a judge. Falsehood puts on a mask. Nothing is hidden under the sun."

"The knowledge of all things is possible"

"Realize that everything connects to everything else."

"The acquisition of knowledge is always of use to the intellect, because it may thus drive out useless things and retain the good. For nothing can be loved or hated unless it is first known."
