Prologue In this dialogue, Euthyphro meets Socrates outside the court of the
King Archon, where Socrates is currently waiting to attend to defend himself against the charges of
Meletus on the grounds of
impiety. Euthyphro faults Meletus for bringing the suit, and tells Socrates that these charges of impiety have resulted because Socrates is always talking about his
daemon, the divine sign which warns him of various courses of action, which the Athenians see as Socrates introducing innovations to their religion. Euthyphro then tells Socrates that, as a prophet, the Athenians also laugh at his divinely inspired predictions and call him crazy, even though the predictions all come true. Euthyphro assures Socrates that he thinks Socrates will defend his case well, and that he believes he will also succeed in his own: he is going to court himself to prosecute his elderly father for murder, because his father bound a worker in chains and left him to die, all despite the fact that his own family believe it is impious for a son to prosecute his father. Socrates is astonished by Euthyphro's confidence, but Euthyphro insists that doing so is pious; as a prophet he would know what piety is. Since Euthyphro seems so assured of himself, and Socrates is facing a trial for impiety, Socrates asks Euthyphro to help him with a definition of "piety" that he can use in his defence.
First definition: piety is prosecuting a wrongdoer Euthyphro's first definition of piety is what he is doing now, that is, prosecuting his father for manslaughter. Socrates rejects this definition, because it is only an
example of piety, not a universally true definition, something that provides the essential characteristic that makes pious actions pious.
Second definition: piety is what is pleasing to the gods Euthyphro's second definition is that Piety is what is
pleasing to the gods. Socrates applauds this definition, because it is expressed in a general form, but criticizes it saying that the gods disagree among themselves as to what is pleasing, so a given action might be both pious and impious at the same time. Euthyphro counters that in his case, the gods would not disagree that someone who kills without justification ought to be punished, but Socrates observes that disputes could still arise over just how much justification actually existed; hence, the same action could be pious and impious.
Third definition: piety is what is pleasing to all the gods Euthyphro's third definition of piety is: "What
all the gods love is pious, and what they
all hate is impious." In reply, Socrates poses what is now called the
Euthyphro dilemma: "Is the pious loved by the gods
because it is pious? Or is it pious because it is loved by the gods?". Euthyphro is unsure, so Socrates elaborates: Is something "beloved" in and of itself, or does it become beloved
when it is loved by someone? Clearly, the answer is the latter, something
becomes beloved when it is loved. So something beloved by the gods becomes so
because it is loved by them, to which Euthyphro agrees. Socrates then reveals his contradiction: What is beloved by the gods cannot be pious: Euthyphro had said that something is loved by the gods
because it is pious, which means that their love follows
from something inherent in the pious. And yet they just agreed that what is beloved is put in that state as a result of being loved. So piety cannot belong to what is beloved by the gods since according to Euthyphro it does not acquire its characteristics by something (the act of being loved), in contrast to the things that are beloved, that are put in this state through the very act of being loved.
Fourth definition: piety is a part of justice Socrates then suggests his own definition of piety, that piety is a part of justice. If piety is what is causing Euthyphro to prosecute his father, what is pious must be just. However, in the same sense that a definition of
even numbers would not be the same as a definition of numbers, there are other actions that are just but not pious, such as courage or concern for others. Euthyphro says that piety is concerned with looking after the gods, but Socrates objects, saying that "looking after", if used in its ordinary sense (with which Euthyphro agrees) would imply that when one performs an act of piety one thus makes one of the gods better – an example of
hubris, a dangerous human emotion frowned upon by the Greek gods. In turn, Euthyphro responds that "looking after" involves service to others, and Socrates asks: What is the end product of piety? Euthyphro replies with his earlier (third) definition, that: Piety is what is loved by all the gods.
Final definition: piety is knowledge of sacrifice and prayer Euthyphro then proposes a final definition: Piety is the knowledge of what sacrifices and prayers are pleasing to the gods. Socrates suggests that this implies that piety is knowledge of a type of commerce: sacrifice is a gift to the gods, and prayers are requests for favours in return, and piety consists in knowing what benefits the gods. Euthyphro objects that the gifts are not a
quid pro quo, between man and deity, but are gifts of "
honour, esteem, and favour", from man to deity. Socrates observes that this is the same as saying that piety is what is pleasing to the gods, which was where the dialogue had begun. Euthyphro concedes that they have made no progress, and Socrates proposes that they start again from the beginning, but Euthyphro excuses himself, stating that he is in a rush. Socrates concludes the dialogue by remarking that, since Euthyphro was unable to teach him about piety, Socrates has received nothing helpful to his defense against a formal charge of impiety. == Reception ==
