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, close to 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, which are horses that never have been domesticated and historically linked to the megafauna category of species. 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.

Horses are adapted to run, allowing them to quickly escape predators, and possess a good sense of balance and a strong fight-or-flight response. Related to this need to flee from predators in the wild is an unusual trait: horses are able to sleep both standing up and lying down, with younger horses tending to sleep significantly more than adults. Female horses, called mares, carry their young for approximately 11 months and a young horse, called a foal, can stand and run shortly following birth. Most domesticated horses begin training under a saddle or in a harness between the ages of two and four. They reach full adult development by age five, and have an average lifespan of between 25 and 30 years.

Horse breeds are loosely divided into three categories based on general temperament: spirited "hot bloods" with speed and endurance; "cold bloods", such as draft horses and some ponies, suitable for slow, heavy work; and "warmbloods", developed from crosses between hot bloods and cold bloods, often focusing on creating breeds for specific riding purposes, particularly in Europe. There are more than 300 breeds of horse in the world today, developed for many different uses.

Horses and humans interact in a wide variety of sport competitions and non-competitive recreational pursuits as well as in working activities such as police work, agriculture, entertainment, and therapy. Horses were historically used in warfare, from which a wide variety of riding and driving techniques developed, using many different styles of equipment and methods of control. Many products are derived from horses, including meat, milk, hide, hair, bone, and pharmaceuticals extracted from the urine of pregnant mares. Humans provide domesticated horses with food, water, and shelter, as well as attention from specialists such as veterinarians and farriers.

Pride is defined by Merriam-Webster as "reasonable self-esteem" or "confidence and satisfaction in oneself". Oxford defines it as "the quality of having an excessively high opinion of oneself or one's own importance." Pride may be related to one's own abilities or achievements, positive characteristics of friends or family, or one's country. Richard Taylor defined pride as "the justified love of oneself", as opposed to false pride or narcissism. Similarly, St. Augustine defined it as "the love of one's own excellence", and Meher Baba called it "the specific feeling through which egoism manifests."

Philosophers and social psychologists have noted that pride is a complex secondary emotion that requires the development of a sense of self and the mastery of relevant conceptual distinctions (e.g. that pride is distinct from happiness and joy) through language-based interaction with others. Some social psychologists identify the nonverbal expression of pride as a means of sending a functional, automatically perceived signal of high social status.

Pride may be considered the opposite of shame or of humility, sometimes as proper or as a virtue and sometimes as corrupt or as a vice. With a positive connotation, pride refers to a content sense of attachment toward one's own or another's choices and actions, or toward a whole group of people and is a product of praise, independent self-reflection and a fulfilled feeling of belonging. Other possible objects of pride are one's ethnicity and one's sex identity (for example LGBT pride). With a negative connotation pride refers to a foolishly and irrationally corrupt sense of one's personal value, status or accomplishments used synonymously with hubris.

While some philosophers such as Aristotle (and George Bernard Shaw) consider pride (but not hubris) a profound virtue, some world religions consider pride's fraudulent form a sin, such as is expressed in Proverbs 11:2 of the Hebrew Bible. In Judaism, pride is called the root of all evil. When viewed as a virtue, pride in one's abilities is known as virtuous pride, greatness of soul, or magnanimity, but when viewed as a vice, it is often known to be self-idolatry, sadistic contempt, vanity or vainglory.
