Christianity

The primary meaning of "happiness" in various European languages involves good fortune, blessing, or a similar happening. The meaning in Greek philosophy refers primarily to ethics.

In Christianity, the ultimate end of human existence consists in felicity, Latin equivalent to the Greek eudaimonia ("blessed happiness"), described by the 13th-century philosopher-theologian Thomas Aquinas as a beatific vision of God's essence in the next life.

According to Augustine of Hippo and Thomas Aquinas, man's last end is happiness: "all men agree in desiring the last end, which is happiness." Aquinas agreed with Aristotle that happiness cannot be reached solely through reasoning about consequences of acts, but also requires a pursuit of good causes for acts, such as habits according to virtue.

According to Aquinas, happiness consists in an "operation of the speculative intellect ": "Consequently happiness consists principally in such an operation, viz. in the contemplation of Divine things." And, "the last end cannot consist in the active life, which pertains to the practical intellect." So: "Therefore the last and perfect happiness, which we await in the life to come, consists entirely in contemplation. But imperfect happiness, such as can be had here, consists first and principally in contemplation, but secondarily, in an operation of the practical intellect directing human actions and passions."

Human complexities, like reason and cognition, can produce well-being or happiness, but such form is limited and transitory. In temporal life, the contemplation of God, the infinitely Beautiful, is the supreme delight of the will. Beatitudo, or perfect happiness, as complete well-being, is to be attained not in this life, but the next.
