The object of this volume is not to cast fresh blame on authorities and individuals, nor is it to expose one nation more than another to accusations … - Arthur Ponsonby, 1st Baron Ponsonby of Shulbrede

War is fought in this fog of falsehood, a great deal of it undiscovered and accepted as truth. The fog arises from fear and is fed by panic. Any attempt to doubt or deny even the most fantastic story has to be condemned at once as unpatriotic, if not traitorous. This allows a free field for the rapid spread of lies. If they were only used to deceive the enemy in the game of war it would not be worth troubling about. But, as the purpose of most of them is to fan indignation and induce the flower of the country's youth to be ready to make the supreme sacrifice, it becomes a serious matter. Exposure, therefore, may be useful, even when the struggle is over, in order to show up the fraud, hypocrisy, and humbug on which all war rests, and the blatant and vulgar devices which have been used for so long to prevent the poor ignorant people from realizing the true meaning of war.

A Government which has decided on embarking on the hazardous and terrible enterprise of war must at the outset present a one-sided case in justification of its action, and cannot afford to admit in any particular whatever the smallest degree of right or reason on the part of the people it has made up its mind to fight. Facts must be distorted, relevant circumstances concealed, and a picture presented which by its crude colouring will persuade the ignorant people that their Government is blameless, their cause is righteous, and that the indisputable wickedness of the enemy has been proved beyond question. A moment's reflection would tell any reasonable person that such obvious bias cannot possibly represent the truth. But the moment's reflection is not allowed; lies are circulated with great rapidity. The unthinking mass accept them and by their excitement sway the rest. The amount of rubbish and humbug that pass under the name of patriotism in war-time in all countries is sufficient to make decent people blush when they are subsequently disillusioned.

In calm retrospect we can appreciate better the disastrous effects of the poison of falsehood, whether officially, semi-officially, or privately manufactured. It has been rightly said that the injection of the poison of hatred into men's minds by means of falsehood is a greater evil in war-time than the actual loss of life. The defilement of the human soul is worse than the destruction of the human body. A fuller realization of this is essential.
