A socially constructed concept of the reality of shared experiences.
What then is truth? A movable host of metaphors, metonymies, and; anthropomorphisms: in short, a sum of human relations which have been poetically and rhetorically intensified, transferred, and embellished, and which, after long usage, seem to a people to be fixed, canonical, and binding.
- Friedrich Nietzsche, On truth and Lies in a Nonmoral Sense
1. Morally depraved, dissolute, bad, vicious, wicked or evil. Unscrupulous, corrupt. A reprobate.
2. Morally wrong, unethical.
Often confused with amoral, unmoral, and nonmoral, of which the first is the most common; immoral simply means bad and defiant of the moral principles of society while amoral means lacking in or indifferent to any morals, neither moral or immoral (neither good or bad).
The necktie psychopath is as immoral as they come, cunningly charming and manipulating their way to the top, indifferent to who they hurt along the way.
Josef Mengele led experiments that led to greater medical understanding... but were stridently immoral and cruel.
