Heroes have gone out; quacks have come in; the reign of quacks has not ended with the nineteenth century. The sceptre is held with a firmer grasp; the empire has a wider boundary. We are all the slaves of quackery in one shape or another. Indeed, one portion of our being is always playing the successful quack to the other.
Thomas CarlyleThe authentic insight and experience of any human soul, were it but insight and experience in hewing of wood and drawing of water, is real knowledge, a real possession and acquirement.
Thomas Carlyle
