Did Mach agree with Berkeley's concept of "to be is to be perceived"?

The statement that Mach agreed with Berkeley's concept of "to be is to be perceived" is accurate. Mach's philosophy involved the idea that our sensations and perceptions are a fundamental basis for understanding reality. Like Berkeley, who posited that existence is contingent upon perception, Mach also emphasized the role of perception in constructing our understanding of existence.

However, while they share similarities in their focus on perception, Mach's views diverged in significant ways, particularly in how he approached the nature of physical reality beyond perception. Mach emphasized experiences and sensations in such a way that reality is informed through their presence, aligning more with a form of scientific empiricism while still considering perception's central role.

Understanding this connection highlights Mach's contributory role in the philosophical discourse surrounding perception and reality, setting the stage for later developments in psychology and epistemology.
