Le monde n'a jamais manqué de charlatans; cette science, de tout temps, fut en professeurs très fertile.
La Fontaine.
He took himself to be no mean Doctour, who being guilty of no Greek, and being demanded why it was called an hectic fever; 'because,' saith he, 'of an hecking cough, which ever attendeth that disease.'
Thomas Fuller, The Holy State.
Man is a dupable animal. Quacks in Medicine, quacks in Religion, and quacks in Politics know this and act upon that knowledge. There is scarcely anyone who may not, like a trout, be taken by tickling.
Robert Southey.
Quack doctors are indeed pompous, self-sufficient, affectedly solemn, venal and unfeeling with a vengeance.
Vicesimus Knox, D.D.
