Final answer:
The statement that Jefferson based the rationale in the Declaration of Independence on John Locke's theories is true, as Locke's ideas on natural rights, government by consent, and the right of revolution heavily influenced Jefferson's writing.
Step-by-step explanation:
The statement that Jefferson’s rationale in the Declaration of Independence came primarily from the theories of John Locke is True. Locke’s philosophy revolved around the concepts of natural rights, which included life, liberty, and property. Jefferson echoed these sentiments in the Declaration of Independence, with a slight modification, mentioning the right to “life, liberty, and the pursuit of happiness.” Locke’s influence on Jefferson is further evidenced by the ideas of government by consent and the belief in the people’s right to revolt against unjust rulers, all of which can be traced back to Locke’s Second Treatise of Government.
