Jungian archetypes are a concept from psychology that refers to a universal, inherited idea, pattern of thought, or image that is present in the collective unconscious of all human beings. The psychic counterpart of instinct, archetypes are thought to be the basis of many of the common themes and symbols that appear in stories, myths, and dreams across different cultures and societies. Some examples of archetypes include those of the mother, the child, the trickster, and the flood, among others.
Eros (ˈɪərɒs, USˈɛrɒs,irɒs,-oʊs; ) is a concept in ancient Greek philosophy referring to sensual or passionate love, from which the term erotic is derived. Eros has also been used in philosophy and psychology in a much wider sense, almost as an equivalent to "life energy". The Protestant philosopher C. S. Lewis posits it as one of the four ancient Greek words for love in Christianity, alongside storge, philia, and agape. In the classical world, erotic love was generally referred to as a kind of madness or theia mania ("madness from the gods").
