If one performs an act beneficial to others with a view to gaining some personal benefit, then it is not an altruistically motivated act. There are several different perspectives on how "benefit" (or "interest") should be defined. A material gain (for example, money, a physical reward, etc.) is clearly a form of benefit, while others identify and include both material and immaterial gains (affection, respect, happiness, satisfaction etc.) as being philosophically identical benefits.

According to psychological egoism, while people can exhibit altruistic behavior, they cannot have altruistic motivations. Psychological egoists would say that while they might very well spend their lives benefitting others with no material benefit (or a material net loss) to themselves, their most basic motive for doing so is always to further their own interests. For example, it would be alleged that the foundational motive behind a person acting this way is to advance their own psychological well-being ("good feelings"). Critics of this theory often reject it on the grounds that it is non-falsifiable; in other words, it is impossible to prove or disprove because immaterial gains such as a "good feelings" cannot be measured or proven to exist in all people performing altruistic acts. Psychological egoism has also been accused of using circular logic: "If a person willingly performs an act, that means he derives personal enjoyment from it; therefore, people only perform acts that give them personal enjoyment". This particular statement is circular because its conclusion is identical to its hypothesis (it assumes that people only perform acts that give them personal enjoyment, and concludes that people only perform acts that give them personal enjoyment).
