Philosophical skepticism is a current of classical philosophy, which is based on doubt. In other words, it can also be described as a critical attitude that systematically objects to the ideal that knowledge and absolute certainty are possible, proposed in general or particular fields. Philosophical skepticism is represented in the school of "Skeptikoi", of those who stated that they did not "affirm nothing, only expressed their opinion"; This current is opposed to philosophical dogmatism which maintains that a group of statements are absolutely unequivocal, authoritative and true.
Philosophical skepticism, in addition, differs from Ordinary Skepticism, whose doubts are raised against certain beliefs or types of beliefs since the certainty that sustains it is weak or poor. Those ordinary skeptics are not credulous or innocent, they do not receive the true things lightly and without first evidencing things to believe. They doubt religious miracles completely, psychoanalysis, alien abductions, etc. but of course they do not express any doubt that knowledge and certainty are possible; thanks to systematic arguments that undermine any claim of knowledge.
Philosophical Skepticism is of great antiquity. Much of what is known about this philosophical current comes from the Greek physician and philosopher Sexto Empirico, an important character in the representation of Pyrrhian skepticism and who also lived around the year 200 and who thought that animals derived from mud, fire, donkeys, fruits, fermented wines, slime and rotten animals.
