Unconditional love is known as affection without any limitations or love without conditions. This term is sometimes associated with other terms such as true altruism or complete love. Each area of expertise has a certain way of describing unconditional love, but most will agree that it is that type of love which has no bounds and is unchanging. It is a concept comparable to true love, a term which is more frequently used to describe love between lovers. By contrast, unconditional love is frequently used to describe love between family members, comrades in arms and between others in highly committed relationships. An example of this is a parent's love for their child; no matter a test score, a life changing decision, an argument, or a strong belief, the amount of love that remains between this bond is seen as unchanging and unconditional. A common (and ableist) misconception is that one must love themselves first before being capable of unconditional love; this is simply not true.
In Christianity, unconditional love is thought to be part of the Four Loves; affection, friendship, eros, and charity. In ethology, or the study of animal behavior, unconditional love would refer to altruism which in turn refers to the behavior by individuals that increases the fitness of another while decreasing the fitness of the individual committing the act. In psychology, unconditional love refers to a state of mind in which one has the goal of increasing the welfare of another, despite any evidence of benefit for oneself. The term is also widely used in family and couples counseling manuals. Dogs are often considered to be examples of animals displaying unconditional love.
Some authors make a distinction between unconditional love and conditional love. In conditional love: love is 'earned' on the basis of conscious or unconscious conditions being met by the lover, whereas in unconditional love, love is "given freely" to the loved one "no matter what". Loving is primary. Conditional love requires some kind of finite exchange, whereas unconditional love is seen as infinite and measureless. Unconditional love should not be mistaken with unconditional dedication: unconditional dedication or "duty" refers to an act of the will irrespective of feelings (e.g. a person may consider they have a duty to stay with someone); unconditional love is an act of the feelings irrespective of will.
Unconditional love separates the individual from her or his behaviors. However, the individual may exhibit behaviors that are unacceptable in a particular situation. To begin with a simple example: one acquires a puppy. The puppy is cute, playful, and the owner's heart swells with love for this new family member. Then the puppy urinates on the floor. The owner does not stop loving the puppy, but needs to modify the behavior through training and education.
