Immanuel Kant is what I suppose one would call a 'practical philosopher' in that he is not primarily concerned with the more abstract thoughts of philosophy. Rather his philosophy, as expressed in this book, is one about how practical philosophy, or practical reason, works. He makes a distinction at the beginning of his book between the subjective and the objective, suggesting that practical reason is about making the subjective objective.

This book begins with a section about defining practical
Hume, by his criticism of the concept of causality, awakened him from his dogmatic slumber—so at least he says, but the awakening was only temporary, and he soon invented a soporific that enabled him to sleep again.
—Bertrand Russell, A History of Western Philosophy

When I first read that opening salvo of Russell’s chapter on Kant, I thought it rather unfair towards the German monk. But now, after digesting Kant’s philosophy a little more, I can’t help but agree. In fact, I more than agree—I think

The first two critiques constitue a unit so far as their main argument goes. The Critique of Pure Reason establishes that while humans can imagine things in themselves (ideas), they can only know things as they are given to them (concepts). The gap between our conceptional understanding and our rational ideas is unbridgeable, requiring, even under the best of circumstances, an infinite induction which we, as finite beings, are incapable of. Furthermore, the First Critique establishes that while ...more

It is difficult to overestimate Kant's influence in philosophy. Even those who reject his explicit theories often use his terms, whether by wondering how it could be possible for something to be "synthetic" (not a matter of meaning) and yet "a priori" (knowable independent of experience), or by asking what is the source of an ethical "imperative." Kant has sometimes been credited for almost single-handedly creating the German philosophical tradition, and it certainly is hard to imagine what Hege ...more
I'm torn by this book. While I appreciate Kant's moral philosophy pivoting around duty (i.e., the worthiness of moral actions out of duty as opposed to out of socialization), the metaphysical "proofs" leave much to be desired. Foremost of these "proofs" is that Kant sees freedom as necessary if duty is to be meaningful. In other words, if we are not free to choose our duty, or if we are fatalistically bound to the choices we only appear to make, then morality for Kant is a hollow form. So, out o ...more

really bizarre and painstaking argument; the anatomy of the moral law and self-conceit is in need of a solution, -- moral cultivation, which rational beings can only drive at as close as one can but never achieve completely. Thus the existence of God (its holiness and perfection) is not a metaphysical being, but a moral necessity. This is a development of transcendental categories of the first critique. Except in morality, there is an immediately connection between the object in the empirical wo ...more

Un renard n’avait jamais vu de lion. Or le hasard le mit un jour en face de ce fauve. Comme il le voyait pour la première fois, il eut une telle frayeur qu’il faillit en mourir. L’ayant rencontré une deuxième fois, il eut peur encore, mais pas autant que la première fois. Mais à la troisième fois qu’il le vit, il s’enhardit jusqu’à s’en approcher et à causer avec lui.
Cette fable d'Esope montre que l’accoutumance adoucit même les choses effrayantes.

I found this work very hard to follow. Kant is differentiating what can be determined by reason. He focuses on discovering what can be determined by will (i.e., there is freedom to select something) vs. what already exists a priori. This search for both flexible and inflexible "truth" leads to a discussion of spirituality, and good and bad. The difference between Kant and others is that Kant seeks to "harmonize" rather than reconcile" philosophical points. The Fundamental Law of Pure, Practical ...more

Good philosophical book for educators. Particularly in the Doctrine of Method, Kant proposes a method for teaching morality. It’s essential to teach the student to act from duty, n not merely outwardly, conforming to morality. Kant recommends that we enlist our pupil's natural delight in arguing about ethical matters n allow him to develop his judgment by asserting various purported moral actions. We’re warned not to either err by presenting examples of overblown heroism as paradigms of morality ...more

Mainly focussed on Appendix 1. Rating based on the deeply annoying and very frequent times when two words have been scanned as one: Kant is hard enough without blasted typos (true, I could spend money and buy a better copy). Never really bought deontology for the very reason that the appendix seeks to address - occurrence of intuitively necessary exceptions - and, to my mind it fails to do so.

In this book, Kant explores the function of the will, free will, and moral reasoning leading to good done as moral duty. Kant shows that the traditional metaphyiscal proofs for the existence of God have been worthless and misleading, because they misapplied the principles of theoretical reasoning beyond their proper sphere (one cannot prove the existence of God using scientific reasoning), thus, giving the impression that theology was a "science" of God. Instead, Kant argues in this book that li ...more

It made me think about the importance of being coherent and congruent with my reality. I love how he mantains its rigourism till the last word of its work. Great if you want to want to think about how is the transition from theory to practice in the areas of ethics, politics and law.
Matthew Frerichs
This book helped to shape my way of examining the world we exist in. I read this for a philosophy class when I attended NDSU when I was 18. Good material and great starting point for those who want to begin thinking about philosophical matters.

So difficult to read. Yet, the basis for much scholarship and judgment.
Boris Gregoric
Very dense and opaque. Brilliant too, of course.
Feb 23, 2014 Lawrence marked it as to-read  ·  review of another edition
I really think the book was OK. Somehow I feel that most people love it for romantic or novel reasons. Or because you're supposed to love this if you're a hardcore philosopher. While I would never deny his contribution to the arena of philosophy, I just can't say I *love* this book. It's interesting and worth the read; much better than spending 2-4 hours watching some silly TV. So if you're deciding between this and TV, then imagine I gave it 4.5 stars ;)
i still can't reconcile myself with his philosophy of moral deontology. the supposed "universal maxim" makes no sense to me. i think morality depends on situations. doing something consistently is not always the right thing to do. his concepts are too far into the realm of abstraction, and although he calls it practical reason, there's nothing practical about it. it refuses to enter into the realm of every day life.
Kitap boyunca "Pratik akil soyledir boyledir, digerisi sudur budur. Ben de cok eminim hep bunlardan." diyip duruyo adam. Deneyci genclik bunu tokatlamistir biraz diye tahmin ediyorum. Nihayetinde soyle bi neticeye vardim ben: Kant, sen kimsin la?
Marcus Lira
I learnt two things: (1) I could actually trust all those lecturers that told me about Kant's ideas and, (2) Immanuel was a clever guy so obsessed about being clear that it makes most of his fascinating ideas look kind of dry. So much for starry skies.
Sort of thing you claim you are reading to sound impressive but you get bored after the first five pages, or whatever the recommended reading was, because there is absolutely no point to reading philosophy unless you're a philosopher.
They say the best meals are often hard and painful to digest, and I thoroughly enjoyed Kant's chef d'ouvre and am still digesting. I can't wait to share my insights on the text once it clears the cognitive tract.
Michelle Jones
The writing itself was terrible and you can find much better written synopses online, so unless you have to read this for class or something, I would just read about Kant's philosophies elsewhere.
The most understandable of Kant's books and the most useful for things other than epistemology. However, it really only makes sense in light of his epistemological critiques.
A thin book with thick material. The pattern of his thought process was much more valuable than the actual particulars. Not sure what a goo audience is for this book.
Kant's view on morals. When he started to talk about christianity at the near end of the book, I was lost. So cheezy, but that was short part of it, thank god.
Melinda Saucedo
this was a really difficult read, but somehow i managed to get through it. Kant's writing infuses Socretes' methodology and current to his day ethic views
