Dadaists believed that society's regulated, authoritative, historical reasoning was delusional, and that the natural world, of which man was a small part, was governed by both logic and chaos.

Rationality, reason, mathematics and science had all been co-opted by the war machine of the First World War. As a consequence, Dadaists considered reason itself to be discredited.

As Jean Arp put it, 'Dada aimed to destroy the reasonable deceptions of man and recover the natural and unreasonable order.'

discredits the entire Age of Enlightenment, calling into question the value of rational thought if all it leads to is war.
