“To govern the state by law is to praise the right and blame the wrong.”

The Second Sex (1949)
Context: It is vain to apportion praise and blame. The truth is that if the vicious circle is so hard to break, it is because the two sexes are each the victim at once of the other and of itself. Between two adversaries confronting each other in their pure liberty, an agreement could be easily reached: the more so as the war profits neither. But the complexity of the whole affair derives from the fact that each camp is giving aid and comfort to the enemy; woman is pursuing a dream of submission, man a dream of identification. Want of authenticity does not pay: each blames the other for the unhappiness he or she has incurred in yielding to the temptations of the easy way; what man and woman loathe in each other is the shattering frustration of each one's own bad faith and baseness.

Perhaps the adjective "elderly" requires definition. In physics, mathematics, and astronautics it means over thirty; in the other disciplines, senile decay is sometimes postponed to the forties. There are, of course, glorious exceptions; but as every researcher just out of college knows, scientists of over fifty are good for nothing but board meetings, and should at all costs be kept out of the laboratory!
