バートランド・ラッセルの名言・警句( Bertrand Russell Quotes )

A man's reasons for wishing to limit his family are generally economic; these reasons operate equally with the woman, but she has her own special reasons as well. The strength of the desire that men feel for children is evident when one considers the loss of material comfort that professional men deliberately incur when they undertake to educate a family in the expensive manner that their class considers necessary.
