Eros ( /ˈɪrɒs/ or /ˈɛrɒs/; Ancient Greek: ἔρως érōs) is one of the four words in Ancient Greek which can be rendered into English as “love”. The other three are storge, philia and agape. Eros refers to “intimate love” or romantic love; storge to familial love; philia applies to close friends; and agape refers to “selfless love”, or “charity” as it is translated in the Christian scriptures (from the Latin caritas, dearness). The term erotic is derived from eros. Eros has also been used in philosophy and psychology in a wider sense, almost as an equivalent to "life energy".

In Ancient Greek, eros means "intimate love". The Modern Greek word is erotas.

In the classical world, erotic love was generally referred to as a kind of madness or theia mania ("madness from the gods"). This love passion was described through an elaborate metaphoric and mythological schema involving "love's arrows" or "love darts", the source of which was often the personified figure of Eros (or his Latin counterpart, Cupid), or another deity (such as Rumor). At times the source of the arrows was said to be the image of the beautiful love object itself. If these arrows were to arrive at the lover's eyes, they would then travel to and 'pierce' or 'wound' his or her heart and overwhelm him/her with desire and longing (love sickness). The image of the "arrow's wound" was sometimes used to create oxymorons and rhetorical antithesis concerning its pleasure and pain.

Eros (/ˈɪərɒs/, US: /ˈɛrɒs/; Ancient Greek: Ἔρως, "Desire"), in Greek mythology, was the Greek god of love. His Roman counterpart was Cupid ("desire"). Some myths make him a primordial god, while in other myths, he is the son of Aphrodite.

The Shaftesbury Memorial in Piccadilly Circus, London, is popularly mistaken for Eros. In fact it represents Anteros.

Eros appears in ancient Greek sources under several different guises. In the earliest sources (the cosmogonies, the earliest philosophers, and the mysteries), he is one of the primordial gods involved in the coming into being of the cosmos. But in later sources, Eros is represented as the son of Aphrodite whose mischievous interventions in the affairs of gods and mortals cause bonds of love to form, often illicitly. Ultimately, in the later satirical poets, he is represented as a blindfolded child, the precursor to the chubby Renaissance cupid – whereas in early Greek poetry and art, Eros was depicted as an adult male who embodies sexual power.

The word concept is defined variously by different sources. Philosophers and others generally agree that concepts are formed from experience and other pre-existing mental content by abstraction and other operations in the brain.

John Locke's description of a general idea corresponds to a description of a concept. According to Locke, a general idea is created by abstracting, drawing away, or removing the uncommon characteristic or characteristics from several particular ideas. The remaining common characteristic is that which is similar to all of the different individuals. For example, the abstract general idea or concept that is designated by the word "red" is that characteristic which is common to apples, cherries, and blood. The abstract general idea or concept that is signified by the word "dog" is the collection of those characteristics which are common to Airedales, Collies, and Chihuahuas.^{[citation needed]}

John Stuart Mill argued that general conceptions are formed through abstraction. A general conception is the common element among the many images of members of a class. "...[W]hen we form a set of phenomena into a class, that is, when we compare them with one another to ascertain in what they agree, some general conception is implied in this mental operation" (A System of Logic, Book IV, Ch. II). Mill did not believe that concepts exist in the mind before the act of abstraction. "It is not a law of our intellect, that, in comparing things with each other and taking note of their agreement, we merely recognize as realized in the outward world something that we already had in our minds. The conception originally found its way to us as the result of such a comparison. It was obtained (in metaphysical phrase) by abstraction from individual things" (Ibid.).

Eros Luciano Walter Ramazzotti (born October 28, 1963), known simply as Eros Ramazzotti, is an Italian musician and singer-songwriter. Ramazzotti is enormously popular in Italy, and is well known in most non-English-speaking European countries and in the Spanish-speaking world, as he has released most of his albums in both Italian and Spanish.

Since 1984, he has released 11 studio albums, one EP, three compilation albums, three live albums, and 37 singles. Ramazzotti has sold over 40 million records in his 25-year career. His repertory includes duets with artists such as Cher, Tina Turner, Andrea Bocelli, Patsy Kensit, Anastacia, Joe Cocker, Ricardo Arjona, Luciano Pavarotti, Laura Pausini, and Ricky Martin.

Ramazzotti first gained international success in 1993, with the release of Tutte storie, which amassed six million album sales and occupied the top five in every country where he had previously released albums. This success led to a BMG International record contract in 1994. His audience appeal comes from several factors, including his unique voice, which can be described as somewhat nasal but nevertheless forceful and resonant, and his energetic delivery of catchy, melodic tunes which are often passionate mid-tempo autobiographical ballads, with instrumentation that is rich in soft-rock influence. Most of his albums have been recorded in both Italian and Spanish.
