“I owe a lot to the opportunities I have had. I think we have a great country, and the day that all people of all races have equal opportunity to be useful to their community, we're going to have a better country.”

Address to Grand Jury (1885)
Context: I am glad that the Crown have proved that I am the leader of the Half-breeds in the North-West. I will perhaps be one day acknowledged as more than a leader of the Half-breeds, and if I am, I will have an opportunity of being acknowledged as a leader of good in this great country.

Context: The word “equality” is often used, but, wisely, rarely defined. The moment one tries to define it, one gets into great difficulty. For example, it cannot mean equality of incomes or earnings; otherwise, we would not need more than one union. Indeed, we would not need one union. If we are to have opportunity, we cannot have equality, because the two are opposite. We may have equality of opportunity, but if the only opportunity is to be equal, it is not opportunity.

Context: From the political point of view there is but a single principle,— the sovereignty of man over himself. This sovereignty of one's self over one's self is called Liberty. Where two or several of these sovereignties associate, the State begins. But in this association there is no abdication. Each sovereignty parts with a certain portion of itself to form the common right. That portion is the same for all. There is equal contribution by all to the joint sovereignty. This identity of concession which each makes to all, is Equality. The common right is nothing more or less than the protection of all, pouring its rays on each. This protection of each by all, is Fraternity.
Liberty is the summit, Equality the base. Equality is not all vegetation on a level, a society of big spears of grass and stunted oaks, a neighborhood of jealousies, emasculating each other. It is, civilly, all aptitudes having equal opportunity; politically, all votes having equal weight; religiously, all consciences having equal rights.
