The End of the World, by John Martin.
To Martin Heidegger, nihilism is the movement whereby "being" is forgotten, and is transformed into value, in other words, the reduction of being to exchange value.[24] Heidegger, in accordance with Nietzsche, saw in the so-called "death of God" a potential source for nihilism:
If God, as the supra-sensory ground and goal, of all reality, is dead; if the supra-sensory world of the Ideas has suffered the loss of its obligatory, and above it, its vitalizing and up-building power, then nothing more remains to which Man can cling, and by which he can orient himself.[26]
The French philosopher Albert Camus asserts that the absurdity of the human condition is that people search for external values and meaning in a world which has none, and is indifferent to them. Camus writes of value-nihilists such as Meursault,[27] but also of values in a nihilistic world, that people can instead strive to be "heroic nihilists", living with dignity in the face of absurdity, living with "secular saintliness", fraternal solidarity, and rebelling against and transcending the world's indifference
The current era has seen radical changes in both formal and popular conceptions of human nature. The knowledge disclosed by modern science has effectively rewritten the relationship of humankind to the natural world. Advances in medicine and technology have freed humans from significant limitations and ailments of previous eras;[29] and philosophy—particularly following the linguistic turn—has altered how the relationships people have with themselves and each other are conceived. Questions about the meaning of life have also seen radical changes, from attempts to reevaluate human existence in biological and scientific terms (as in pragmatism and logical positivism) to efforts to meta-theorize about meaning-making as a personal, individual-driven activity (existentialism, secular humanism).

Pragmatism, originated in the late-19th-century U.S., to concern itself (mostly) with truth, positing that "only in struggling with the environment" do data, and derived theories, have meaning, and that consequences, like utility and practicality, are also components of truth. Moreover, pragmatism posits that anything useful and practical is not always true, arguing that what most contributes to the most human good in the long course is true. In practice, theoretical claims must be practically verifiable, i.e. one should be able to predict and test claims, and, that, ultimately, the needs of mankind should guide human intellectual inquiry.
Pragmatic philosophers suggest that the practical, useful understanding of life is more important than searching for an impractical abstract truth about life. William James argued that truth could be made, but not sought.[30][31] To a pragmatist, the meaning of life is discoverable only via experience.

work, Kant gives the example of a person who seeks to borrow money without intending to pay it back. This is a contradiction because if it were a universal action, no person would lend money anymore as he knows that he will never be paid back. The maxim of this action, says Kant, results in a contradiction in conceivability (and thus contradicts perfect duty). Kant also denied that the c

Kantianism is a philosophy based on the ethical, epistemological, and metaphysical works of Immanuel Kant. Kant is known for his deontological theory where there is a single moral obligation, the "Categorical Imperative", derived from the concept of duty. Kantians believe all actions are performed in accordance with some underlying maxim or principle, and for actions to be ethical, they must adhere to the categorical imperative.
Simply put, the test is that one must universalize the maxim (imagine that all people acted in this way) and then see if it would still be possible to perform the maxim in the world without contradiction. In Groundwork, Kant gives the example of a person who seeks to borrow money without intending to pay it back. This is a contradiction because if it were a universal action, no person would lend money anymore as he knows that he will never be paid back. The maxim of this action, says Kant, results in a contradiction in conceivability (and thus contradicts perfect duty).
Kant also denied that the consequences of an act in any way contribute to the moral worth of that act, his reasoning being that the physical world is outside one's full control and thus one cannot be held accountable for the events that occur in it.


The origins of utilitarianism can be traced back as far as Epicurus, but, as a school of thought, it is credited to Jeremy Bentham,[22] who found that "nature has placed mankind under the governance of two sovereign masters, pain and pleasure", then, from that moral insight, deriving the Rule of Utility: "that the good is whatever brings the greatest happiness to the greatest number of people". He defined the meaning of life as the "greatest happiness principle".
Jeremy Bentham's foremost proponent was James Mill, a significant philosopher in his day, and father of John Stuart Mill. The younger Mill was educated per Bentham's principles, including transcribing and summarizing much of his father's work.[23]
Nihilism


Nihilism suggests that life is without objective meaning.
Friedrich Nietzsche characterized nihilism as emptying the world, and especially human existence, of meaning, purpose, comprehensible truth, and essential value; succinctly, nihilism is the process of "the devaluing of the highest values".[24] Seeing the nihilist as a natural result of the idea that God is dead, and insisting it was something to overcome, his questioning of the nihilist's life-negating values returned meaning to the Earth.[25]
