Heraclitus
Numeration from Diels' edition; translation by Malcolm Wilson

61.  The sea is water most pure and most polluted.  For fish it is drinkable and their salvation; but for men it is undrinkable and their death.

106. Heraclitus found fault with Hesiod who distinguished good days from bad days, on the grounds that he did not know that there was a single nature for every day.

58.  The doctors cut and cauterize and torture in every way those who are in bad health, and they demand a payment from the sick, though they don't deserve it.

51.  Nor do they understand how that which is different agrees with itself.  It is a back-bending attunement like that of the bow and the lyre

41. It is not possible to step twice into the same river.

12. In the same rivers different and different waters flow.

49a.  We walk and we do not walk into the same rivers; we are and we are not.

 80.  One must know that war is common and that justice is strife, and that everything comes to be in accordance with strife and necessity.

53.  War is the father of all things; of all things it is the king; and it shows some to be gods, others to be men, it makes some slaves and some free.

102.  To god all things are beautiful and good and just, but men have supposed that some things are unjust and others are just.

83.  The wisest of men will seem like an ape in comparison to god, in wisdom and beauty and in everything else.    

82. The most beautiful of the apes is ugly in comparison with the race of men.

54.  The unapparent attunement is more powerful than the apparent.

123.  Nature loves to hide.

93.  The lord, whose oracle is in Delphi, neither speaks nor hides, but points out.

34.  Those who do not understand, when they hear are like the deaf.  The saying is true of them - though present they are absent.

17.  Many people, whenever they come across such things, cannot conceive them, nor do they know them after they have learned them, but they think they do.

 88.  It is the same thing in us - living and dead, awake and sleeping, young and old. For by changing the former are the latter, and by changing again the latter are the former.

21.  Death is what we see when we are awake; sleep what we see when we are sleeping.

1. Of this reasoning, which always exists, men are uncomprehending both before they hear and after having heard for the first time.  For though everything occurs in accordance with this reasoning, they are like novices, testing such words and deeds as I lay out, distinguishing each one and saying how it is.  But other men fail to notice what they do when they are awake, just as what they forget when asleep.

73.  One must not act and speak as if one were asleep.

89.  The cosmos is one and common for those who are awake.

2.  Therefore it is necessary to follow the common, that is, what is shared.  For the shared is the common.  But though reasoning is common, the majority of men live as if they had a private understanding.

41. Wisdom is one thing, to know the thought by which everything is guided through everything.

50. It is wise, after having listened not to me, but to the reasoning, to agree that everything is one.

75.  The sleepers are workers and coworkers of the things that come to pass in the cosmos.

119.  Character is a man's divine spirit.

101.  I have investigated myself.
