“I cannot consent to take the position that the door of hope — the door of opportunity — is to be shut upon any man, no matter how worthy, purely upon the grounds of race or color. Such an attitude would, according to my convictions, be fundamentally wrong.”
Letter to James Adger Smythe http://www.theodorerooseveltcenter.org/Research/Digital-Library/Record.aspx?libID=o266191 (26 November 1902), as quoted in speech by Edward de Veaux Morrell https://cdn.loc.gov/service/rbc/lcrbmrp/t2609/t2609.pdf (April 1904)

Context: I do not intend to appoint any unfit man to office. So far as I legitimately can I shall always endeavor to pay regard to the wishes and feelings of the people of each locality, but I cannot consent to take the position that the door of hope — the door of opportunity — is to be shut upon any man, no matter how worthy, purely upon the grounds of race or color. Such an attitude would, according to my convictions, be fundamentally wrong.

Context: It is probably true that the large majority of the fortunes that now exist in this country have been amassed not by injuring our people, but as an incident to the conferring of great benefits upon the community; and this, no matter what may have been the conscious purpose of those amassing them. There is but the scantiest justification for most of the outcry against the men of wealth as such; and it ought to be unnecessary to state that any appeal which directly or indirectly leads to suspicion and hatred among ourselves, which tends to limit opportunity, and therefore to shut the door of success against poor men of talent, and, finally, which entails the possibility of lawlessness and violence, is an attack upon the fundamental properties of American citizenship.
