Delivered by Lincoln during the American Civil War, the Gettysburg Address examines the founding principles of the United States as stated in the 1776 Declaration of Independence. A score is comprised of twenty units. Given in 1863, the reference to "Four score and seven years" refers to a period of 87 years (1863 - 87 years = 1776).

Four score and seven years ago our fathers brought forth on this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal. Now we are engaged in a great civil war, testing whether that nation, or any nation so conceived and so dedicated, can long endure. We are met on a great battlefield of that war. We have come to dedicate a portion of that field, as a final resting place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this. But, in a larger sense, we can not dedicate - we can not consecrate - we can not hallow - this ground. The brave men, living and dead, who struggled here, have consecrated it, far above our poor power to add or detract. The world will little note, nor long remember what we say here, but it can never forget what they did here. It is for us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. It is rather for us to be here dedicated to the great task remaining before us - that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion - that we here highly resolve that these dead shall not have died in vain - that this nation, under God, shall have a new birth of freedom - and that government of the people, by the people, for the people, shall not perish from the earth.

Every man is a valuable member of society who by his observations, researches, and experiments procures knowledge for men.. It is in his knowledge that man has found his greatness and his happiness the high superiority which he holds over the other animals who inhabit the earth with him, and consequently no ignorance is probably without loss to him no error without evil ... The particle and the planet are subject to the same laws and what is learned of one will be known of the other ... I bequeath the whole of my property ... to the United States of America to found at Washington, under the name of the Smithsonian Institution an establishment for the increase and diffusion of knowledge among men.

James Smithson 1765 - 1829
Founder of the Smithsonian Institution

Human brain size evolved most rapidly during a time of dramatic climate change. Larger, more complex brains enabled early humans of this time period to interact with each other and with their surroundings in new and different ways. As the environment became more unpredictable, bigger brains helped our ancestors survive.

We hold these truths to be self-evident: that all men are created equal, that they are endowed by their creator with certain inalienable rights. Among these are life, liberty and the pursuit of happiness, that to secure these rights governments are instituted among men. We - solemnly publish and declare, that these colonies are and of right ought to be free and independent states - and for the support of this declaration, with a firm reliance on the protection of divine providence, we mutually pledge our lives, our fortunes and our sacred honour.
