Quote by Friedrich Engels
Thus, as far as he is a scientific man, as far as he anything, he is a materialist; outside his science, in spheres about which he knows nothing, he translates his ignorance into Greek and calls it agnosticism.
Summary
This quote suggests that a scientific individual, when it comes to their field of expertise, follows a materialistic perspective. However, outside their area of knowledge, they resort to labeling their lack of understanding as agnosticism. Essentially, the quote implies that scientists tend to apply a materialistic approach to explain what they know, but when faced with unfamiliar territories, they rely on the term "agnosticism" to mask their lack of expertise or ignorance.
