“If we spoke a different language, we would perceive a somewhat different world.”
This actually first appears in Recent Experiments in Psychology (1950) by Leland Whitney Crafts, Théodore Christian Schneirla, and Elsa Elizabeth Robinson, where it is expressed:
: If we used a different vocabulary or if we spoke a different language, we would perceive a somewhat different world.
Randy Allen Harris, in Rhetoric and Incommensurability (2005), p. 35, and an endnote on p. 138 indicates the misattribution seems to have originated in a misreading of quotes in Patterns Of Discovery: An Inquiry Into The Conceptual Foundations of Science (1958) by Norwood Russell Hanson, where an actual quotation of WIttgenstein on p. 184 is followed by one from the book on psychology.
