Between 1424 and 1433 he worked on the translation of the Lives and Opinions of Eminent Philosophers by Diogenes Laërtius, which came to be widely circulated in manuscript form and was published at Rome in 1472 ( the first printed edition of the Lives ; the Greek text was printed only in 1533 ).

** Diogenes Laërtius, Vitae philosophorum ( Lives and Opinions of Eminent Philosophers )

The main source for the life of Heraclitus is Diogenes Laërtius, although some have questioned the validity of his account as " a tissue of Hellenistic anecdotes, most of them obviously fabricated on the basis of statements in the preserved fragments.

Timon of Phlius calls him " the riddler " ( ainiktēs ) according to Diogenes Laërtius, who had just explained that Heraclitus wrote his book " rather unclearly " ( asaphesteron ) so that only the " capable " should attempt it.

Diogenes Laërtius ascribes to Theophrastus the theory that Heraclitus did not complete some of his works because of melancholia.

Diogenes Laërtius divides the physiologoi into two groups, Ionian and Italiote, led by Anaximander and Pythagoras, respectively.

The knowledge we have of them derives from accounts of later philosophical writers ( especially Aristotle, Plutarch, Diogenes Laërtius, Stobaeus and Simplicius ), and some early theologians, ( especially Clement of Alexandria and Hippolytus of Rome ).

Most of the details known about his life come from the anecdotes preserved by Diogenes Laërtius in his Lives and Opinions of Eminent Philosophers.

According to Persaeus ( Diogenes Laërtius vii.

A plausible chronology for his life is as follows: He was born 334 / 3 BC, and came to Athens in 312 / 11 BC at the age of 22 ( Diogenes Laërtius, vii.

He studied philosophy for about 10 years ( Diogenes Laërtius, vii.

Diogenes Laërtius gives two different accounts of his death.

Around 387 BC, at the age of 23, he traveled with the physician Theomedon, who according to Diogenes Laërtius some believed was his lover, to Athens to study with the followers of Socrates.

Diogenes Laërtius, however, wrote that Protagoras invented the “ Socratic ” method.

But most modern scholars, following the suggestion of Diogenes Laërtius, consider them to be forgeries, some forged by the philosopher Heraclides Ponticus, others by or altered by Christian writers:

Diogenes Laërtius preserves several different accounts of this story ; one of them has Crates giving his money away to the citizens of Thebes, apparently after seeing the beggar king Telephus in a tragedy ; whereas another account has him placing his money in the hands of a banker, with the agreement that he should deliver it to his sons, unless they too became philosophers, in which case he should distribute it among the poor.

Crates wrote a book of letters on philosophical subjects, the style of which is compared by Diogenes Laërtius to that of Plato ; but these no longer survive.

Diogenes Laërtius says that his works filled ten volumes, but of these, only fragments remain.

Most of the biographical information we have of Theophrastus was provided by Diogenes Laërtius ' Lives of the Philosophers, written more than four hundred years after Theophrastus ' time.

From the lists of Diogenes Laërtius, giving 227 titles, it appears that the activity of Theophrastus extended over the whole field of contemporary knowledge.

The passage in which the above occurs has been described as " elaborately ironical ", making it unclear which of its aspects may be taken seriously, although Diogenes Laertius later confirms that there were indeed seven such individuals who were held in high esteem for their wisdom well before Plato's time.

On the other hand, modern scholars advise that we treat Diogenes ' testimonia with care, especially when he fails to cite his sources: " Diogenes has acquired an importance out of all proportion to his merits because the loss of many primary sources and of the earlier secondary compilations has accidentally left him the chief continuous source for the history of Greek philosophy.

It has been suggested that Diogenes was an Epicurean, or a Skeptic.

Some scholars, drawing on the discovery of defaced coins from Sinope dating from the period 350-340 BCE, believe that Diogenes only moved to Athens after the death of Antisthenes, and it has been argued that the stories linking Antisthenes to Diogenes were invented by the Stoics in a later period in order to provide a succession linking Socrates to Zeno, via Antisthenes, Diogenes, and Crates.

The village of Bricket Wood has been host to at least six naturist clubs: Fiveacres Country Club, Spielplatz, The Sun-Folk Society, Gardenia ( originally named Silverbirch ), Diogenes Sunlight Society ( also known as The Phoenix Recreational Society ), and The Suncampers.

Of these, Gardenia has now closed and been built on, Diogenes became the Diogenes Sun Club when it moved to near Maple Cross.

It seems that Xenophon's portrayal of her in his Symposium has been the most influential: Diogenes Laërtius, for example, seems to quote the Symposium passage, though he does not mention Xenophon by name, and the term " Xanthippe " has now come to mean any nagging scolding person, especially a shrewish wife.

Very little is known about him as none of his works have survived, though he has been mentioned and discussed in detail by Photius ( in his Myriobiblion ) and Sextus Empiricus, and also to a lesser extent by Diogenes Laertius and Philo of Alexandria.

None of Diogenes ’ many writings has survived, but details of his life come in the form of anecdotes ( chreia ), especially from Diogenes Laërtius, in his book Lives and Opinions of Eminent Philosophers.

Diogenes ' name has been applied to a behavioural disorder characterised by involuntary self-neglect and hoarding .< ref >

One of the dialogues attributed to Lucian, his avowed imitator, who frequently mentions him, is called Menippus, but since the sub-title (" The Oracle of the Dead ") resembles that of a work ascribed to Menippus by Diogenes Laërtius, it has been suggested that it is imitated from his Necromancy.

They include four orations on Kingship addressed to Trajan on the virtues of a sovereign ; four on the character of Diogenes of Sinope, on the troubles to which men expose themselves by deserting the path of Nature, and on the difficulties which a sovereign has to encounter ; essays on slavery and freedom ; on the means of attaining eminence as an orator ; political discourses addressed to various towns which he sometimes praises and sometimes blames, but always with moderation and wisdom ; on subjects of ethics and practical philosophy, which he treats in a popular and attractive manner ; and lastly, orations on mythical subjects and show-speeches.

Amazon John has returned from exile in 1979, and Diogenes Arruda dies of heart attack in the car on the way to a political act.

He has now presented his story at the Diogenes Club to Mycroft, who asks his brother Sherlock to look into it.

The only surviving complete works by Epicurus are three letters, which are to be found in book X of Diogenes Laertius ' Lives of Eminent Philosophers, and two groups of quotes: the Principal Doctrines, reported as well in Diogenes ' book X, and the Vatican Sayings, preserved in a manuscript from the Vatican Library.

Under his guidance the school flourished greatly — there were at one period more than 2000 students, Diogenes affirms, and at his death, according to the terms of his will preserved by Diogenes, he bequeathed to it his garden with house and colonnades as a permanent seat of instruction.

Diogenes Laërtius says that he left behind Commentaries, which consisted of 30, 000 lines ; but of these only fragments have been preserved.

He wrote some fifty works, of which only fragments have survived preserved by writers such as Diogenes Laërtius, Stobaeus, Cicero, Seneca and Plutarch.

This work, judging by the quotations preserved by Diogenes Laërtius, was filled with spicy anecdotes about philosophers and their supposed taste for boy-lovers and courtesans.

An anecdote written by Metrocles concerning Diogenes is preserved by Laërtius:

His chief work is the Successions of Philosophers drawn from personal knowledge, with considerable fragments preserved in Athenaeus and Diogenes Laërtius.
