• Kant's philosophy - The happy life: Practical idealism and the constantly cheerful heart
    Jun 27 2026

    In theoretical regard Kant dismisses the idealism that declares the world to be a mere illusion. Practically, however, we should act as if it was true: We should consider the brevity and vanity of life, treat the world as a children's game and not take anything as important except our moral duty. This is the path to a constantly cheerful heart.


    Quote: 0:08

    Nothing in life has value except our morality: 0:22

    Life is short and fleeting: 27:54

    Mere life, measured by its pleasure, is worthless: 34:43

    Practical idealism: 54:18

    The power of imagination as condition of the possibility of practical idealism: 1:21:41

    The constantly cheerful heart: 1:51:44

    Abstraction as means to a happy life: 2:01:00

    Thanks: 2:22:23


    The posture of practical idealism and the constantly cheerful heart Kant discusses mainly in his works on anthropology, so in his Anthropology from a pragmatic point of view: http://korpora.org/kant/aa07/230.html, his lectures on anthropology: https://archive.org/details/kantsgesammeltes0000kant_a3n3 | https://archive.org/details/kantsgesammeltes0000kant_j8c0 and his handwritten estate on anthropology: http://korpora.org/kant/aa15/234.html.

  • Kant's philosophy - Kant's Epicureanism: Modesty as key to a happy life
    Jun 20 2026

    Each inclination is a chain. It binds us to the objects which we need for satisfying it. And the more we satisfy it the more we become dependent on it through habit and also get numb towards the pleasure. Whoever wants to be happy therefore should not chase after satisfaction of his needs but strive for having as little needs as possible. Kant recommends along with Epicurus a modest life: Don’t deny yourself delights, don’t live in complete asceticism, but be content with little and simple delights, enjoy other pleasures from time to time when there is an opportunity, but don’t make yourself dependent on them.


    Quote: 0:08

    The positive path towards happiness: Get what you require: 0:38

    The negative path towards happiness: Require little: 19:10

    Modesty instead of wantoness: 26:21

    People should be able to do without, but not actually do without everything: 38:36

    Whoever is dependent on things is immoral and unhappy: 1:04:14

    Kant's advices: 1:35:26

    - Abstain from futile desires: 1:36:13

    - Think how many live without whatever is a need to you: 1:39:54

    - Don’t let habits turn into inclinations through habit: 1:46:31

    - Always keep some pleasures in prospect for later: 2:08:18

    - Don’t sacrifice the whole for a part: 2:22:20

    - Keep in mind that every gain is a loss and the other way around: 2:30:54

    Conclusion: 2:41:24

    Thanks: 2:45:16

  • Kant's philosophy - Kant's stoicism: Equanimity as key to a happy life
    Jun 13 2026

    People's misery mostly doesn't come from outside difficulties or blows of fate but from them letting things affect their mood too much and being too sensitive. Against this Kant advises a stoic equanimity: Allowing no thing an influence on one's psyche, not being sad about anything except one's own bad behaviour. This however doesn't mean indifference: A person should be sentimental and should take things to heart, that is let himself be moved, but they should not rob him of his peace of mind.


    Quote: 0:08

    People aren't victims of their affections and passions: 1:29

    The wise person does not need to overcome himself but isn't at war with himself in the first place: 13:25

    People ought to be equanimous, not indifferent: 22:39

    People ought to take things to heart, not let them affect their mood: 31:46

    People ought to be sentimental, not sensitive: 51:55

    True equanimity comes from character: 1:02:40

    The oversensitivness of the present is an issue of civilization: 1:20:09

    Equanimity does not go together with hedonism: 1:38:07

  • Kant's philosophy - Affections & passions and how they stand in the way of a happy life
    Jun 6 2026

    A person should tame their affections and passions. This is a moral duty, for through them you harm others but also lose your own reason and through this your freedom and your human dignity. It however is also advised pragmatically, for the affections and passions bring all kinds of misery upon people, an equanimous life which is free of them therefore is a more happy life.


    Quote: 0:08

    Happiness we attain through independence: 0:58

    Affections: 8:57

    Passions: 33:36

    The similarities between affections and passions: 49:48

    The differences of affections and passions: 54:40

    Passions are always directed at people: 58:58

    Classification of passions: 1:12:37

    1. Material passions: 1:22:35

    2. Formal passions: 1:33:01

    - The passions for honour, power and money: 2:08:25

    The purpose of affections and passions: 2:27:09

    Passions come about through the power of imagination: 2:47:24

  • Kant's philosophy - Morality doesn't demand pleasure-hating asceticism, but an always cheerful heart
    May 30 2026

    For a long time practical philosophy was considered the doctrine of the good life and of happiness. Morality was often considered a part of this or also a means to reach happiness. Kant's accomplishment lies in having strictly distinguished both. The proper or pure practical philosophy only deals with moral duty in his system, unconcerned with our personal adventage or happiness. Nevertheless Kant also in many places made remarks about what a good life consists of. And the cliché of Kant only preaching and himself living cold, joyless dutifulness is not true: Sensuality and our desires according to him should be governed by reason, but not supressed, rather they should get their due.


    Quote: 0:08

    The place of the doctrine of good life in the architectonic of Kant's system: 0:35

    A universally valid doctrine of happiness is not possible: 13:48

    Kant's remarks on happiness are less original than other parts of his thinking: 24:17

    Kant did not reject sensuality and pleasure in the name of morality: 28:13

    Morality and prudence mostly align: 57:33

    Kant stands for moral rigorism but not moral purism: 1:09:06

    Virtue is strength and courage and therefore not grumpy but cheerful: 1:25:40

    Kant himself enjoyed his life: 1:43:23

    Moral duty should be done for its own sake, not because it is adventagous to us: 2:01:34

  • Kant's philosophy - Animal ethics: Why animals are items without rights & still mustn't be abused
    May 23 2026

    Kant's position towards animals is often attacked but usually completely misunderstood. According to him we don't have duties towards animals but still duties in regards to animals. From the standpoint of right they are items, meaning they can be possessed and and used and have no rights just as they have no duties. Still we ought to treat them with care. Not for their but for our own sake: Because it would not befit our own human dignity to not behave like rational beings and not act in a purposeful manner. Kant's moral philosophy therefore is one that not only forbids treating animals disregardingly but even to treat lifeless objects disregardingly.


    Quote: 0:08

    Kant's position towards animals: 1:55

    The nature of animals: 10:41

    - The faculty of cognition of animals: 21:51

    - The feelings of animals: 45:17

    - The faculty of desiring of animals: 1:03:50

    - The souls of animals and their life after death: 1:13:09

    The criticism of Kant's position: 1:16:37

    Animals are items without rights: 1:34:54

    Kant rejects animal abuse: 1:54:19

    Kant is not anthropocentric but ratiocentric: 2:06:36

    We mustn't abuse animals because otherwise we become numb: 2:21:11

    We mustn't abuse animals out of reverence for ourselves: 2:26:39

    Reverence for ourselves indeed is the reason people treat animals regardingly, even if they aren't aware of it: 2:36:35

    Why people really reject Kant's moral philosophy in regards to animals: 2:52:52

    A person ought to not be possessed by the spirit of destruction: 3:00:01

    The duties in regards to animals are wide duties and left to our own discretion: 3:24:33

    Everything ought to be a matter of conscience to us: 3:32:57

  • Kant's philosophy - Cosmopolitan right: Refugees & colonialism
    May 16 2026

    The state of nature is a war of all against all. Only public right can create perpetual peace. There must be laws which secure for each his own, and these laws must be binding and enforced. States right is supposed to create peace between individuals, the right of nations is supposed to bring peace between states. But for such a states right and right of nations to be able to be established there first needs to be a global cosmopolitan right: There mustn't be total war of all against all after all, rather every human being must have a universal right of visitation. For only if someone who does not belong to a legal community und is not protected through the laws governing it, has the opportunity to at least offer joining it, can a legal community ever come into being in the first place.

  • Kant's philosophy - Peace needs republicanism
    May 9 2026

    Perpetual peace between states is possible if these enter into a federation of nations and submit to binding international law. For this to be possible two conditions should be met inside the states: There should be freedom of thought so that criticism and proposals for reaching perpetual peace are possible, and the sate should have a republican consitution so that wars are only possible with the approval of the people that has to wage them.


    Quote: 0:08

    Peace through right: 2:54
