time, a significant discourse on learning and communication for individuals with hearing disabilities. In the text, Desloges, who himself is deaf and mute, defends the use of sign language for educating the deaf, arguing against the approach taken by Abbé Deschamps that emphasizes oral communication through the visual observation of speech movements. Desloges provides personal insights and experiences, illustrating how sign language has served as a natural and efficient means of communication among the deaf community. He critiques Deschamps's method as overly complex and difficult, suggesting instead that sign language allows for clarity and precision in expressing a wide range of ideas, making it more suited for effectively educating deaf individuals. Through his observations, Desloges highlights the richness of sign language, asserting it as a valid and necessary component of educational practices for the deaf.
