False.
“They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.”
This was written by Franklin, sometime shortly before February 17, 1775 as part of his notes for a proposition at the Pennsylvania Assembly, as published in Memoirs of the life and writings of Benjamin Franklin (1818).
A variant of this was published as:
“Those who would give up Essential Liberty to purchase a little Temporary Safety, deserve neither Liberty nor Safety.”
This was used as a motto on the title page of An Historical Review of the Constitution and Government of Pennsylvania. (1759); the book was published by Franklin; its author was Richard Jackson, but Franklin did claim responsibility for some small excerpts that were used in it.
