The phrase "acquiesce in the necessity" appears in the Declaration of Independence, in a passage where the writers explain why they feel compelled to declare independence from Great Britain. The full passage reads:
"Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security. Such has been the patient sufferance of these Colonies; and such is now the necessity which constrains them to alter their former Systems of Government. The history of the present King of Great Britain is a history of repeated injuries and usurpations, all having in direct object the establishment of an absolute Tyranny over these States. To prove this, let Facts be submitted to a candid world...We must, therefore, acquiesce in the necessity, which denounces our Separation, and hold them, as we hold the rest of mankind, Enemies in War, in Peace Friends."
The phrase "acquiesce in the necessity" conveys that the writers of the Declaration of Independence believe that declaring independence from Great Britain is not a choice, but a necessity. They feel that the abuses and usurpations committed by the British government have left them with no other option but to declare their independence and provide new guards for their future security. The use of the word "acquiesce" suggests that the writers are reluctantly accepting the situation, rather than actively seeking it out. Overall, the phrase underscores the seriousness of the writers' decision to declare independence and the gravity of the situation that led to it.
