“Don't give up! I believe in you all.
A person's a person, no matter how small!
And you very small persons will not have to die
If you make yourselves heard! So come on, now, and TRY!”

Interview with Luxemburger Wort (2015)

A very similar statement has become attributed to Benjamin Franklin, but apparently only in recent decades: "A man wrapped up in himself makes a very small bundle." This seems to have been first attributed to Franklin in The New Age Magazine Vol. 66 (1958), and the earliest appearance of it yet located is in Coronet magazine, Vol. 34 (1953), p. 27, where it was attributed to a Louise Stein.

Context: LIBERATION LEADS TO LIBERATION. These are the first words of truth — not truth in quotation marks but truth in the real meaning of the word; truth which is not merely theoretical, not simply a word, but truth that can be realized in practice. The meaning behind these words may be explained as follows:
By liberation is meant the liberation which is the aim of all schools, all religions, at all times.
This liberation can indeed be very great. All men desire it and strive after it. But it cannot be attained without the first liberation, a lesser liberation. The great liberation is liberation from influences outside us. The lesser liberation is liberation from influences within us.
At first, for beginners, this lesser liberation appears to be very great, for a beginner depends very little on external influences. Only a man who has already become free of inner influences falls under external influences.
Inner influences prevent a man from falling under external influences. Maybe it is for the best. Inner influences and inner slavery come from many varied sources and many independent factors — independent in that sometimes it is one thing and sometimes another, for we have many enemies.
There are so many of these enemies that life would not be long enough to struggle with each of them and free ourselves from each one separately. So we must find a method, a line of work, which will enable us simultaneously to destroy the greatest possible number of enemies within us from which these influences come.
I said that we have many independent enemies, but the chief and most active are vanity and self-love. One teaching even calls them representatives and messengers of the devil himself.
For some reason they are also called Mrs. Vanity and Mr. Self-Love.
As I have said, there are many enemies. I have mentioned only these two as the most fundamental. At the moment it is hard to enumerate them all. It would be difficult to work on each of them directly and specifically, and it would take too much time since there are so many. So we have to deal with them indirectly in order to free ourselves from several at once.
These representatives of the devil stand unceasingly at the threshold which separates us from the outside, and prevent not only good but also bad external influences from entering. Thus they have a good side as well as a bad side.
For a man who wishes to discriminate among the influences he receives, it is an advantage to have these watchmen. But if a man wishes all influences to enter, no matter what they may be — for it is impossible to select only the good ones — he must liberate himself as much as possible, and finally altogether, from these watchmen, whom some considerable undesirable.
For this there are many methods, and a great number of means. Personally I would advise you to try freeing yourselves and to do so without unnecessary theorizing, by simple reasoning, active reasoning, within yourselves.
