“[Our goal was to] translate aspects of culture never successfully recorded by the scientist, although often caught by the artist, into some form of communication sufficiently clear and sufficiently unequivocal to satisfy the requirements of scientific enquiry.”

Often the portion of this passage on "Towering genius..." is quoted without any mention or acknowledgment that Lincoln was speaking of the need to sometimes hold the ambitions of such genius in check, when individuals aim at their own personal aggrandizement rather than the common good.
1830s, The Lyceum Address (1838)
Context: It is to deny, what the history of the world tells us is true, to suppose that men of ambition and talents will not continue to spring up amongst us. And, when they do, they will as naturally seek the gratification of their ruling passion, as others have so done before them. The question then, is, can that gratification be found in supporting and maintaining an edifice that has been erected by others? Most certainly it cannot. Many great and good men sufficiently qualified for any task they should undertake, may ever be found, whose ambition would inspire to nothing beyond a seat in Congress, a gubernatorial or a presidential chair; but such belong not to the family of the lion, or the tribe of the eagle. What! think you these places would satisfy an Alexander, a Caesar, or a Napoleon? — Never! Towering genius disdains a beaten path. It seeks regions hitherto unexplored. — It sees no distinction in adding story to story, upon the monuments of fame, erected to the memory of others. It denies that it is glory enough to serve under any chief. It scorns to tread in the footsteps of any predecessor, however illustrious. It thirsts and burns for distinction; and, if possible, it will have it, whether at the expense of emancipating slaves, or enslaving freemen. Is it unreasonable then to expect, that some man possessed of the loftiest genius, coupled with ambition sufficient to push it to its utmost stretch, will at some time, spring up among us? And when such a one does, it will require the people to be united with each other, attached to the government and laws, and generally intelligent, to successfully frustrate his designs.

Context: Communication technologies are necessary, but not sufficient, for us humans to get along with each other. This is why we still have many disputes and conflicts in the world. Technology tools help us to gather and disseminate information, but we also need qualities like tolerance and compassion to achieve greater understanding between peoples and nations.
I have great faith in optimism as a guiding principle, if only because it offers us the opportunity of creating a self-fulfilling prophecy. So I hope we've learnt something from the most barbaric century in history — the 20th. I would like to see us overcome our tribal divisions and begin to think and act as if we were one family. That would be real globalisation…

1820s, Letter to A. Coray (1823)
Context: But, whatever be the constitution, great care must be taken to provide a mode of amendment, when experience or change of circumstances shall have manifested that any part of it is unadapted to the good of the nation. In some of our States it requires a new authority from the whole people, acting by their representatives, chosen for this express purpose, and assembled in convention. This is found ' too difficult for remedying the imperfections which experience develops from time to time in an organization of the first impression. A greater facility of amendment is certainly requisite to maintain it in a course of action accommodated to the times and changes through which we are ever passing. In England the constitution may be altered by a single act of the legislature, which amounts to the having no constitution at all. In some of our States, an act passed by two different legislatures, chosen by the people, at different and successive elections, is sufficient to make a change in the constitution. As this mode may be rendered more or less easy, by requiring the approbation of fewer or more successive legislatures, according to the degree of difficulty thought sufficient, and yet safe, it is evidently the best principle which can be adopted for constitutional amendments.
