Alone we can do so little; together we can do so much.

The aphorism contrasts the limited reach of solitary effort with the amplified power of coordinated work. It suggests that human achievement is not merely additive but multiplicative when people pool skills, knowledge, and support—an idea that resonates with Keller’s own life, in which communication, education, and public advocacy depended on networks of assistance and shared purpose. The quote functions as a compact argument for solidarity: individual talent matters, but durable change and large undertakings typically require cooperation. Its enduring popularity reflects how easily it applies to civic movements, workplaces, and personal relationships alike.
