"It will, of course, be understood that directly or indirectly, soon or late, every advance in the sciences of human nature will contribute to our success in controlling human nature and changing it to the advantage of the common weal"

Edward Thorndike's quote underscores an extensive belief in the transformative potential of scientific progress, especially within the worlds of psychology and the social sciences. Thorndike, a pioneering figure in educational psychology, suggests that as we acquire a deeper understanding of human nature through clinical questions, we inherently boost our capability to influence and form it. This capacity for impact can be seen as both a direct and indirect effect of scientific development-- direct in terms of instant applications and discoveries that enable intervention, and indirect in regards to the unfolding ramifications of these findings in time.

The phrase "quickly or late" highlights the long-lasting nature of clinical development. Not every development will yield immediate changes, but each adds to an incremental body of knowledge. Collectively, these advances form a detailed framework that cultivates our capability to manage and assist human habits better.

Thorndike's mention of the "advantage of the common weal" indicates an utilitarian point of view, stressing that the ultimate objective of understanding and managing humanity ought to be the improvement of society as a whole. This reflects the progressive principles of early 20th-century thinkers who believed in the power of science to solve social issues and enhance human conditions.

Yet, Thorndike's vision is not without its intricacies. The idea of "controlling and altering" humanity can evoke ethical considerations and concerns about intent, approval, and the definition of "common good". Who decides what makes up a helpful change, and how do we balance individual liberties with social development? These questions remain crucial in contemporary discourse as we continue to harness scientific improvements to shape human habits, stressing the need for ethical frameworks to assist these efforts.

In essence, Thorndike points to an optimistic yet cautiously reflective trajectory for the sciences of human nature, promoting for their function in developing a more advantageous future for all of humankind.
