who said we hold the truths to be self evident
All men are created equal In 1776 the Second Continental Congress asked Benjamin Franklin, Thomas Jefferson, John Adams, Robert Livingston, and Roger Sherman to write the Declaration of Independence. This Committee of Five voted to have Thomas Jefferson write the document. After Jefferson finished he gave the document to Franklin to proof. Franklin suggested minor changes, and one of them stands out far more than the others. Jefferson had written, "We hold these truths to be sacred and un-deniable..." Franklin changed it to, "We hold these truths to be self-evident."
Cogito, ergo sum Cogito, ergo sum[a] is a Latin philosophical proposition by René Descartes usually translated into English as "I think, therefore I am". The phrase originally appeared in French as je pense, donc je suis in his Discourse on the Method, so as to reach a wider audience than Latin would have allowed.[1] It appeared in Latin in his later Principles of Philosophy. As Descartes explained, "we cannot doubt of our existence while we doubt...." A fuller version, articulated by Antoine Léonard Thomas, aptly captures Descartes’s intent: dubito, ergo cogito, ergo sum ("I doubt, therefore I think, therefore I am").[b][c] The concept is also sometimes known as the cogito.[2]
