Difficult but totally worth the effort
As in the other Platonic dialogues, Socrates continues to ask the definition of a single virtue: courage in Laches and temperance (sophrosyne) in Charmides. I won't go over all the details of their elenchus, as it's probably summarized in many cliffnotes already. I would like to make some comments regarding the two dialogues.
Although Charmides is more subtle and much more complicated than Laches in its logic and approach, the two dialogues both try to elucidate what we actually mean by a single virtue. First of all, I would like to address a major issue in Plato's theory of virtue, that is if virtue is truly in a 'single' form. Could virtue be in more than one form, or OUGHT it have just a single form? Are they really just shadows of the true single idea of virtue if they are variegated with different aspects?
In the end of their discussion, the respondents who first claimed to 'know' what the repective virtues are failed to answer it and reveal their ignorance and thus their lack of these virtues. This raises another question: Do these virtues truly have to be a 'knowledge' of something? Does the ignorance or inability to define these virtues automatically disqualify them as possessors of these virtues?
Socrates introduces us to the concept of the tinos-word that appears to be complete by itself but actually is not. The word needs another word to explain itself. So, 'knowledge' should be backed up by another word that explains 'of what' the knowledge is: eg. 'knowledge' of 'good and evil'. He also distinguishes the first-order art (science) from the second-order art. The first-order art has a recognizable scope and object, whereas the second-order art deals with the first-order art as its scope of art. Critias regards temperance as the knowledge of the first-order art such as medicine and the second-order art of good and evil, but comes to the moment of aporia. Like many Platonian dialogues, the solution to the problem is inconclusive and instead brings the epiphany of ignorance in order to stimulate his newfound urge to discover the truth.
Whether the virtue questioned is courage or temperance, and whether the participants in the dialogue are frustrated with the conclusion, the answer seems to lie in the aporia itself and hints that all these virtues are different 'aspects' of the single 'form' or 'knowledge' of the good and evil.
This reminded me of all the various branches of knowledge such as history, economics, physics, philosophy, biology, chemistry, psychology, etc. Although they each seem to dealing with different objects in such distinct ways, they seem to be diverging pathways to the common goal of truth. Our world of scientific research gives grants to research that seem to be done for the sake of research only under the misconception of science as the virtue and not as the neutral means to attain that object. Even our most acclaimed political and military policies are jumbled up results of our confusion of the second-order art of distinguishing the good and evil with the first-order art. They make us question the two important virtues, courage and temperance, and we should all ask ourselves the actual aim and the extent of our knowledge.
I also noticed how both Laches and Charmides are less articulate or acquainted with Socrates' dialectic method than their respective partners, Nicias and Critias. However, they both are more honest in admiting their ignorance and are more eager to discover the truth. This attitude of acknowledging one's ignorance is the gate opening up the real possibilities of discovering the truth and is emphasized in many of the dialogues. The false 'belief' in our knowledge is the toughest barrier to attaining a true education and a virtuous life. Nothing is worse than a confident know-nothing know-it-all. :-) So keep those questions alive and coming!
1 Corinthians 3:18
Do not deceive yourselves. If any of you think you are wise by the standards of this age, you should become "fools" so that you may become wise.
p.s. I wish the IRB or any ethical committee reads this when they are contemplating whether any new scientific research is actually good or not.
