Maxwell's Address to the British Association - September 1870

In his letter to Lizzy, Charles talks about the influence Maxwell's writings have had on him. It is due to Maxwell that he has come to believe that:

scientific truth should be presented in different forms, and should be regarded as equally scientific whether it appears in the robust form and the vivid coloring of a physical illustration, or in the tenuity and paleness of a symbolical expression

The above is an excerpt from an address Maxwell delivered to the British Association in 1870. It is a short speech, full of lovely thoughts and phrases, well worth reading in its entirety.
