Final answer:
Jefferson lists three self-evident truths in the Declaration of Independence: equality of men, unalienable rights given by the Creator, and the rights to life, liberty, and the pursuit of happiness.
Step-by-step explanation:
Thomas Jefferson declares in the Declaration of Independence that there are several self-evident truths. Specifically, he mentions three fundamental truths: that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, and that among these rights are Life, Liberty and the pursuit of Happiness. The purpose of governments, as Jefferson states, is to secure these rights, with powers that are derived from the consent of the governed.
