Tell me if anything was ever done... Tell me... Tell me. - Leonardo da Vinci

The men of experiment are like the ant; they only collect and use. But the bee gathers its materials from the flowers of the garden and of the field, but transforms and digests it by a power of its own.

Shadow partakes of the nature of universal matter. All such matters are more powerful in their beginning and grow weaker towards the end, I say at the beginning, whatever their form or condition may be and whether visible or invisible. And it is not from small beginnings that they grow to a great size in time; as it might be a great oak which has a feeble beginning from a small acorn. Yet I may say that the oak is most powerful at its beginning, that is where it springs from the earth, which is where it is largest.

Do not reveal, if liberty is precious to you; my face is the prison of love.
