Modern skepticism can trace its origins back as far as ancient Greece. Where today the term can refer to a doctrine or a method of critical inquiry or be regarded as synonymous with scientific investigation, its foundations lie in an epistemol-ogy that denies the possibility of absolute truth and is based instead on the fallibility of the senses and the necessity of reason to better understand why we see what we do.
