He who loves practice without theory is like the sailor who boards ship without a rudder and compass and never knows where he may cast.
只热爱实践而无理论的人，就像没有舵和罗盘的水手，永远不知道他可能漂流到哪里。

It has always seemed strange to me... the things we admire in men, kindness and generosity, openness, honesty, understanding and feeling, are the concomitants of failure in our system.

And while men admire the quality of the first they love the produce of the second.
