A term used by Andrew Jackson Davis to signify wicked, ignorant,
or undeveloped spirits. Davis believed that at death no
sudden or violent change takes place in the character and disposition
of an individual. Those who were mischievous, unprincipled,
or lascivious during their lives remained so, for a time
at least, after they died. The American Spiritualist Hudson
Tuttle stated, ‘‘As the spirit enters the spirit world just as it
leaves this, there must be an innumerable host of low, undeveloped,
uneducated, or in other words, evil spirits.’’ Davis believed
there was a special sphere or plane for these diakka where
they were put on probation. He said they were responsible for
the fraud and trickery often witnessed at séances; they not only
deceived the sitters, but the medium as well. Davis believed the
way to avoid their influence is to live a pure, refined, and religious
life, for these evil spirits are naturally attracted to those
whose minds most resemble their own.
