Nothing can have value without being an object of utility.

If something has to be designed and invented, and you have to figure out how to ensure that the value of the thing you create is greater than the cost of the inputs, then that is probably my core skill.

Value, therefore, does not stalk about with a label describing what it is.

The value of a thing sometimes lies not in what one attains with it, but in what one pays for it - what it costs us.

We do not place especial value on the possession of a virtue until we notice its total absence in our opponent.

The value of a man should be seen in what he gives and not in what he is able to receive.
