《思想的力量:哲学导论》
363. Aristotle认为我们天生就有的最重要的或最高目标,就是获取幸福,因为只有幸福是我们仅仅因其本身而追求它的。所以幸福就是我们最高的善。
他推出,幸福包含两部分内容:享受(快乐),以及理性能力的运用和提供。对于理性能力的运用是幸福的最重要的组成部分。他坚持认为,仅仅快乐还不足以构成幸福。
这种对理性独特能力的运用,就是Aristotle所说的德性。他著名的论断:幸福就是合乎德性的行动。
德性分两种:理智的德性(积极运用理性能力,去研究自然或就某事作出计划);道德的德性(运用理性能力来调节、平衡冲动和欲望)
364. 《尼各马可伦理学》(Nicomachean Ethics)Aristotle的伦理学著作,很大一部分就是在分析特殊的道德德性。
他说那是两端之间的中道(mean between extremes)(如,勇气就是恐惧一切和毫无恐惧之间的中道)
德性必须成为习惯(即一个人如果仅仅偶尔运用他的理性能力,他就没有承担起他应负的职责,即他没有德性)
他的洞见:人的快乐揭示了他真正的道德品性。
365. 工具性目的(instrumental end):做某件事是把它当作达到别的目的的手段。
自为的目的(intrinsic end):我们为了这件事本身而做这件事。

Blockchain:
22.
Creative and copyright records
Copyright and creative records can be secured and authenticated, keeping a tab on copyright misuse and licensing.
One premier example of this is KodakCoin, which is a photographer-oriented cryptocurrency based on blockchain, launched to be used for payments of licensing photographs.
University degree records
Verification, authentication, and inspection is hard. It is highly prone to theft and misuse. Blockchain can offer a great semi-private access to the records, making sure signing of degrees is done digitally using blockchain.
Gradual record keeping of degrees and scores will benefit efficient utilization of resources as well as proper distribution and ease in inspection process.
The preceding are just some of the varied use cases of blockchain, apart from Bitcoins and alternative cryptocurrencies. In the coming chapters, we will be discussing these points in much more detail.
Challenges
As with any technology, there are various challenges and limitations of blockchain technology. It is important to address these challenges and come up with a more robust, reliable, and resourceful solution for all. Let's briefly discuss each of these challenges and their solutions.
Complexity
Blockchain is complex to understand and easy to implement.
However, with widespread awareness and discussions, this might be made easier in the future.
