Theophrastus
Theophrastus (; grc-gre, Θεόφραστος ; c. 371c. 287 BC), a Greek philosopher and the successor to Aristotle in the Peripatetic school. He was a native of Eresos in Lesbos.Gavin Hardy and Laurence Totelin, ''Ancient Botany'', Routledge, 2015, p. 8. His given name was Tyrtamus (); his nickname (or 'godly phrased') was given by Aristotle, his teacher, for his "divine style of expression". He came to Athens at a young age and initially studied in Plato's school. After Plato's death, he attached himself to Aristotle who took to Theophrastus in his writings. When Aristotle fled Athens, Theophrastus took over as head of the Lyceum. Theophrastus presided over the Peripatetic school for thirty-six years, during which time the school flourished greatly. He is often considered the father of botany for his works on plants. After his death, the Athenians honoured him with a public funeral. His successor as head of the school was Strato of Lampsacus.

Historia Plantarum (Theophrastus Book)
Theophrastus's ''Enquiry into Plants'' or ''Historia Plantarum'' ( grc-gre, Περὶ φυτῶν ἱστορία, ''Peri phyton historia'') was, along with his mentor Aristotle's ''History of Animals'', Pliny the Elder's '' Natural History'' and Dioscorides's ''De materia medica'', one of the most important books of natural history written in ancient times, and like them it was influential in the Renaissance. Theophrastus looks at plant structure, reproduction and growth; the varieties of plant around the world; wood; wild and cultivated plants; and their uses. Book 9 in particular, on the medicinal uses of plants, is one of the first herbals, describing juices, gums and resins extracted from plants, and how to gather them. ''Historia Plantarum'' was written some time between c. 350 BC and c. 287 BC in ten volumes, of which nine survive. In the book, Theophrastus described plants by their uses, and attempted a biological classification based on how plants reproduced, a first i ...

Aristotle
Aristotle (; grc-gre, Ἀριστοτέλης ''Aristotélēs'', ; 384–322 BC) was a Greek philosopher and polymath during the Classical period in Ancient Greece. Taught by Plato, he was the founder of the Peripatetic school of philosophy within the Lyceum and the wider Aristotelian tradition. His writings cover many subjects including physics, biology, zoology, metaphysics, logic, ethics, aesthetics, poetry, theatre, music, rhetoric, psychology, linguistics, economics, politics, meteorology, geology, and government. Aristotle provided a complex synthesis of the various philosophies existing prior to him. It was above all from his teachings that the West inherited its intellectual lexicon, as well as problems and methods of inquiry. As a result, his philosophy has exerted a unique influence on almost every form of knowledge in the West and it continues to be a subject of contemporary philosophical discussion. Little is known about his life. Aristotle was born in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lyceum (classical)
The Lyceum ( grc, Λύκειον, Lykeion) was a temple dedicated to Apollo Lyceus ("Apollo the wolf-god"). It was best known for the Peripatetic school of philosophy founded there by Aristotle in 334 BC. Aristotle fled Athens in 323 BC, and the university continued to function after his lifetime under a series of leaders until the Roman general Sulla destroyed it during his assault on Athens in 86 BC. The remains of the Lyceum were discovered in modern Athens in 1996 in a park behind the Hellenic Parliament. The Lyceum The Lyceum had been used for philosophical debate long before Aristotle. Philosophers such as Prodicus of Ceos, Protagoras, and numerous rhapsodes had spoken there. The most famous philosophers to teach there were Isocrates, Plato (of The Academy), and the best-known Athenian teacher, Socrates.Stenudd, Stefan"Aristotle: His Life, Time, and Work" Stennud.

Peripatetic School
The Peripatetic school was a school of philosophy in Ancient Greece. Its teachings derived from its founder, Aristotle (384–322 BC), and ''peripatetic'' is an adjective ascribed to his followers. The school dates from around 335 BC when Aristotle began teaching in the Lyceum. It was an informal institution whose members conducted philosophical and scientific inquiries. After the middle of the 3rd century BC, the school fell into a decline, and it was not until the Roman era that there was a revival. Later members of the school concentrated on preserving and commenting on Aristotle's works rather than extending them; it died out in the 3rd century. The study of Aristotle's works by scholars who were called Peripatetics continued through late antiquity, the Middle Ages, and the Renaissance. After the fall of the Western Roman Empire, the works of the Peripatetic school were lost to the Latin West, but they were preserved in Byzantium and also incorporated into early Islamic phil ...

Strato Of Lampsacus
Strato of Lampsacus (; grc-gre, Στράτων ὁ Λαμψακηνός, Strátōn ho Lampsakēnós, – ) was a Peripatetic philosopher, and the third director (scholarch) of the Lyceum after the death of Theophrastus. He devoted himself especially to the study of natural science, and increased the naturalistic elements in Aristotle's thought to such an extent, that he denied the need for an active god to construct the universe, preferring to place the government of the universe in the unconscious force of nature alone. Life Strato, son of Arcesilaus or Arcesius, was born at Lampsacus between 340 and 330 BCE. He might have known Epicurus during his period of teaching in Lampsacus between 310 and 306 BCE. He attended Aristotle's school in Athens, after which he went to Egypt as tutor to Ptolemy, where he also taught Aristarchus of Samos. He returned to Athens after the death of Theophrastus (c. 287 BCE), succeeding him as head of the Lyceum. He died sometime between 270 and 268 ...

Hypothetical Syllogism
In classical logic, a hypothetical syllogism is a valid argument form, a syllogism with a conditional statement for one or both of its premises. An example in English: :If I do not wake up, then I cannot go to work. :If I cannot go to work, then I will not get paid. :Therefore, if I do not wake up, then I will not get paid. The term originated with Theophrastus. Propositional logic In propositional logic, hypothetical syllogism is the name of a valid rule of inference (often abbreviated HS and sometimes also called the chain argument, chain rule, or the principle of transitivity of implication). The rule may be stated: :\frac where the rule is that whenever instances of "P \to Q", and "Q \to R" appear on lines of a proof, "P \to R" can be placed on a subsequent line. Hypothetical syllogism is closely related and similar to disjunctive syllogism, in that it is also a type of syllogism, and also the name of a rule of inference. Applicability The rule of hypothetical syllogi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botany
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning " pasture", " herbs" "grass", or " fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – ed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prosleptic Syllogism
A prosleptic syllogism (; from Greek πρόσληψις ''proslepsis'' "taking in addition") is a class of syllogisms that use a prosleptic proposition as one of the premises. The term originated with Theophrastus. in Encyclopædia Britannica Online

Biology
Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life. Energy processing is also important to life as it allows organisms to move, grow, and reproduce. Finally, all organisms are able to regulate their own internal environments. Biologists are able to study life at multiple levels of organization, from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations.Based on definition from: Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use. Like other scientists, biologists use the sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Modus Tollens
In propositional logic, ''modus tollens'' () (MT), also known as ''modus tollendo tollens'' (Latin for "method of removing by taking away") and denying the consequent, is a deductive argument form and a rule of inference. ''Modus tollens'' takes the form of "If P, then Q. Not Q. Therefore, not P." It is an application of the general truth that if a statement is true, then so is its contrapositive. The form shows that inference from ''P implies Q'' to ''the negation of Q implies the negation of P'' is a valid argument. The history of the inference rule ''modus tollens'' goes back to antiquity. The first to explicitly describe the argument form ''modus tollens'' was Theophrastus. ''Modus tollens'' is closely related to '' modus ponens''. There are two similar, but invalid, forms of argument: affirming the consequent and denying the antecedent. See also contraposition and proof by contrapositive. Explanation The form of a ''modus tollens'' argument resembles a syllog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
