- The horse (Equus ferus caballus) is a domesticated, one-toed, hoofed mammal. It belongs to the taxonomic family Equidae and is one of two extant subspecies of Equus ferus. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature, Eohippus, into the large, single-toed animal of today. Humans began domesticating horses around 4000 BCE, and their domestication is believed to have been widespread by 3000 BCE. Horses in the subspecies caballus are domesticated, although some domesticated populations live in the wild as feral horses. These feral populations are not true wild horses, as this term is used to describe horses that have never been domesticated. There is an extensive, specialized vocabulary used to describe equine-related concepts, covering everything from anatomy to life stages, size, colors, markings, breeds, locomotion, and behavior.
- Knight of faith (Wikipedia)
The knight of faith (Danish: troens ridder) is an individual who has placed complete faith in himself and in God and can act freely and independently from the world. The 19th-century Danish philosopher Søren Kierkegaard vicariously discusses the knight of faith in several of his pseudonymic works, with the most in-depth and detailed critique exposited in Fear and Trembling and in Repetition.
