The real source of separation is ultimately a spiritual one. We cannot walk with another unless we are agreed. The lapse of friendship is often due to this, that one has let the other travel on alone. If one has sought pleasure, and the other has sought truth; if one has cumbered his life with the trivial and the petty, and the other has filled his with high thoughts and noble aspirations; if their hearts are on different levels, it is natural that they should now be apart. We cannot stay behind with the camp-followers, and at the same time fight in the van with the heroes. If we would keep our best friends, we must go with them in sympathy, and be able to share their thoughts. In the letters of Dean Stanley, there is one from Jowett to Stanley, which brings out this necessity. "I earnestly hope that the friendship, which commenced between us many years ago, may be a blessing to last us through life. I feel that if it is to be so we must both go onward, otherwise the tear and wear of life, and the 'having travelled over each other's minds,' and a thousand accidents will be sufficient to break it off. I have often felt the inability to converse with you, but never for an instant the least alienation. There is no one who would not think me happy in having such a friend." It is not, however, so much the equal pace of the mind which is necessary, as the equal pace of the spirit. We may think about a very brilliant friend that he will outstrip us, and outgrow us. The fear is natural, but if there be spiritual oneness it is an unfounded fear. Yet oft, when sundown skirts the moor, An inner trouble I behold, A spectral doubt which makes me cold, That I should be thy mate no more. But love is not dependent on intellect. The great bond of union is not that both parties are alike in mind, but that they are akin in soul. Mere intellect only divides men further than the ordinary natural and artificial distinctions that already exist. There are endless instances of this disuniting influence to be seen, in the contempt of learning for ignorance, the derisive attitude which knowledge assumes toward simplicity, the metropolitan disdain for provincial Galilee, the _rabies theologica_ which is ever ready to declare that this people that knoweth not the law is accursed. It is love, not logic, which can unite men. Love is the one solvent to break down all barriers, and love has other grounds for its existence than merely intellectual ones. So that although similarity of taste is another bond and is perhaps necessary for the perfect friendship, it is not its foundation; and if the foundation be not undermined, there is no reason why difference of mental power should wreck the structure.
