William Walker Atkinson 
The Art Of Logical Thinking 

By the employment of the reasoning faculties of the mind we compare objects presented to the mind as percepts or concepts, taking up the 'raw materials’ of thought and weaving them into more complex and elaborate mental fabrics which we call abstract and general ideas of truth. Brooks says: 'It is the thinking power of the mind; the faculty which gives us what has been called thought-knowledge, in distinction from sense-knowledge. It may be regarded as the mental architect among the faculties; it transforms the material furnished by the senses … into new products, and thus builds up the temples of science and philosophy.’
