思想的清晰性是通往哲学真理的第一步。

Sustainability isn't a trend—it's a responsibility we owe to future generations.

I will tell you what I will do and what I will not do. I will not serve that in which I no longer believe whether it call itself my home, my fatherland, or my church: and I will try to express myself in some mode of life or art as freely as I can and as wholly as I can, using for my defence the only arms I allow myself to use—silence, exile, and cunning.

The unexamined life is not worth living.
