Controversy
The proof of the parallelogram of force was not generally accepted without some controversy. Various proofs were developed (chiefly Duchayla's and Poisson's), and these also caused objections. That the parallelogram of force was true was not questioned; why it was true was. This continued throughout the 19th century and into the early 20th.

Famous quotes containing the word controversy:
“Ours was a highly activist administration, with a lot of controversy involved ... but I’m not sure that it would be inconsistent with my own political nature to do it differently if I had it to do all over again.”
—Jimmy Carter (James Earl Carter, Jr.)
“And therefore, as when there is a controversy in an account, the parties must by their own accord, set up for right Reason, the Reason of some Arbitrator, or Judge, to whose sentence, they will both stand, or their controversy must either come to blows, or be undecided, for want of a right Reason constituted by Nature; so is it also in all debates of what kind soever.”
—Thomas Hobbes (1579–1688)
