Thoughts without content are empty, intuitions without concepts are blind... The understanding can intuit nothing, the senses can think nothing. Only through their union can knowledge arise.
In strict science, all persons underlie the same condition of an infinite remoteness. Shall we fear to cool our love by mining forthe metaphysical foundation of this elysian temple? Shall I not be as real as the things I see? If I am, I shall not fear to know them for what they are.
Our knowledge springs from two fundamental sources of the mind; the first is the capacity of receiving representations (receptivity for impressions), the second is the power of knowing an object through these representations (spontaneity [in the production] of concepts).
But we are not dedicating or building any Capitol or Pyramid to human Pride, but found a holy temple in the human Intellect, on the model of the Universe... For whatever is worthy of Existence is worthy of Knowledge-which is the Image (or Echo) of Existence.
