Tudo o que não puder contar como fez, não faça! - Immanuel Kant

Dare to know! Have the courage to use your own intelligence!

It is so easy to be immature. If I have a book to serve as my understanding, a pastor to serve as my conscience, a physician to determine my diet for me, and so on, I need not exert myself at all. I need not think, if only I can pay: others will readily undertake the irksome work for me.

Пребывай с самим собой наедине, и тогда ты узнаешь, сколь ты беден духом.
